The baby’s room

The tradition’s first year and the paediatricians’ agree on the room and disagree on almost nothing else. The fetus spirit that stops a household drilling while a woman is expecting; the confinement month, its closed warm room and what the research makes of it; the bed mother and the cot she guards; where the cot goes, by the safe-sleep guidance and the command position; the first year’s rites, from the third-day bath to the choosing test; and the room a child grows out of.

A birth is the one event for which the tradition kept a room, a calendar and a god at once: the almanac watched the house for nine months, the mother kept to a closed room for thirty days, the bed mother guarded the cot, and the first year was marked off in feasts. The paediatricians keep a shorter list, and it turns out to be the same room. This guide gives the tradition’s first year and the safe-sleep guidance side by side, draws the room they agree on, and says what to do with the parts of the tradition that were about a world without heating and antibiotics.

Before the birth

The almanac watches an expecting household. Every day’s column in the tong shu gives the position of the fetus spirit, the tai shen, in a part of the house, the door, the stove, the bed, the mill, the window, the toilet, moving with the sixty-day cycle the choosing a day essay gives, and the rule is that the place named is not hammered, drilled, moved or knocked that day, and that a household expecting a child does not build, renovate or move house at all if it can wait; Palmer’s translation of the almanac gives the line, and the moving house and building guides give it its place. The tradition’s reasons are the spirit’s; the plain reason is that a pregnant woman should not be carrying furniture through dust, and the calendar was the household’s way of making the rule hold against a husband with a hammer. The room itself is prepared in the last month and not before, which is a custom the tradition shares with most of the world, and the cot, in the folk rule, is not set up until the child is in the house.

The room

Plan 01 A room for a baby A room of three metres sixty by three, with the door in the bottom wall at the right and the window in the top wall. The cot stands against the solid left wall with its head to it, out of the door’s line and a metre from the window and the radiator beneath it, which the paediatricians ask for the cold draught and the tradition for the same reason; nothing hangs over it, no shelf, no beam, no mobile within reach. For the first months the parents’ bed shares the room, drawn dashed, so that the cot is in view of the pillow, which is the safe-sleep guidance and the tradition’s confinement month in one plan. The changing table stands by the door with the light switch at hand, and the nursing chair takes the corner with a wall behind it and both the door and the cot in view, which is the command position for the one person in the house who is awake at three in the morning.

The room the tradition and the paediatricians agree on is drawn above. The safe-sleep guidance of the American Academy of Pediatrics, revised in 2022, asks for the child on its back on a firm flat surface with nothing soft or loose in the cot, in the parents’ room and not in their bed for at least the first six months, in a room that is not overheated; the tradition asks for the child in the confinement room with the mother for the month and in the parents’ room after it, in a cot with its head to a solid wall, away from the window and the door’s line, with nothing hanging over it, in a room kept warm and closed. The two lists are one room. The cot goes against the solid wall with its head to it, which is the bed placement guide’s rule at a small scale; out of the line of the door, so that what comes in does not come straight at the sleeper; a metre from the window and the radiator beneath it, for the draught and the heat; and with nothing over it, no shelf, no beam, no mobile or cord within reach, which is the beams guide’s rule and the safe-sleep list’s in one. The parents’ bed stands where the cot can be seen from the pillow, which is the guidance’s room-sharing and the tradition’s month. The nursing chair takes the corner with a wall behind and the door and the cot in view, the command position for the one person in the house who is awake at three in the morning, and the changing table stands by the door with the light switch at hand and a light that can be dimmed.

Evidence · Warm, dark, quiet, in the room

The guidance has fewer numbers than the tradition’s feeling would suggest, and the honest thing is to say which. Overheating is a risk factor the safe-sleep studies found, and the Academy asks for a room that is not overheated and a child dressed for the room rather than a room heated for the child — but it gives no temperature, and says why: the studies that found the risk defined overheating in different ways, and a single figure cannot be drawn from them. A reader who wants one will find sixteen to twenty degrees in the British safe-sleep advice; it is not the Academy’s, and the site does not put on its plan a number it cannot source. The tradition’s hot room was for a mother in an unheated house, and it is the one part of the month a warm flat has already provided. The child’s sleep is set by light like everyone’s, and the circadian research the sleep guide gives applies from the first weeks: daylight in the morning, dim warm light for the night feeds, no screen in the room. Paruthi and colleagues’ consensus gives twelve to sixteen hours a day, naps counted, for the months from four to twelve, and deliberately gives none for the months before them, because the normal range is too wide to name one — which is worth knowing in the room this guide is about, since it is mostly the room of those first months. The World Health Organization’s night noise guideline, which the quiet guide draws, is for the whole household but was written with the lightest sleepers in mind. Room-sharing without bed-sharing for the first six months is the recommendation with the strongest evidence behind it, and it is also, exactly, the tradition’s month and its sequel.

The cot, with its distances

1Head to the solid wall, no shelf, picture or beam above · 2 A metre from the window and the radiator under it
3Out of the door’s line · 4 The blind cord tied up out of reach, the cot not beside it
5The parents’ bed, the cot seen from the pillow · 6 Nothing in the cot: no bumper, pillow, quilt or toy

Plan 02 The cot, with its distances The parents’ room for the first six months, four metres by three and a half, with the cot placed by the two lists at once. The cot stands against the solid wall with its head to it, which is the bed placement guide’s rule at a small scale, and nothing hangs above it, no shelf, no picture, no beam; a mobile, if there is one, is out of reach. It stands a metre from the window and the radiator beneath it, for the draught and the heat; that metre is the site’s convention and not a safety standard, since no guidance gives a distance, and it is drawn at about where a radiator stops being felt on the hand. It stands out of the door’s line, so that the door opens onto the room and not onto the sleeper. The blind cord is tied up out of reach and the cot is not beside it, which the safety guidance treats as the room’s one strangulation hazard. The parents’ bed stands where the cot is seen from the pillow, the first condition of room-sharing without bed-sharing. Inside the cot there is nothing but the child on a firm flat mattress: no bumper, no pillow, no quilt, no toy, which is the safe-sleep list’s and the tradition’s, since the tradition hung its charms on the wall and never in the bed.

The plan above is the room of the first six months drawn with the distances on it, because the two lists, the tradition’s and the paediatricians’, become one plan only when they are measured. The cot stands against the solid wall with its head to it and nothing above it, which the tradition asked for the same reason it asks it of every bed, and which the safety guidance asks because a shelf, a picture or a mobile within reach is the room’s one falling hazard. A metre from the window and the radiator beneath it keeps the child out of the draught the tradition feared and out of the heat the safe-sleep studies found, since overheating is one of the risk factors the American Academy of Pediatrics lists. The metre is the site’s own and not anybody’s standard: no safe-sleep guidance gives a distance, because the right one depends on the radiator, the window and the room, and this one was chosen because it is about where a radiator’s warmth stops being felt on the hand and where the cold air falling off a window has spread. It is a drawing’s convention, useful for placing a cot on paper, and a reader with a hot old radiator should stand further off. Out of the door’s line is the command position at a small scale, and it is also the practical rule that the door should open onto the room and not onto the cot. The blind cord tied up out of reach, and the cot placed where a cord cannot be reached from it, is the guidance’s own item and has no traditional counterpart; the site gives it the fourth mark because it belongs on the plan. The parents’ bed stands where the cot is seen from the pillow, which is the whole of room-sharing, and the tradition’s bed placement rule for the parents is unchanged by it. Inside the cot there is nothing but the child on a firm flat mattress, and here the two lists agree most exactly: the tradition hung its charms, the tiger hat, the bells and the red thread, on the wall or on the child and never in the bed, and the guidance asks for no bumper, no pillow, no quilt and no toy for the same reason, that a small sleeper should have nothing near its face.

The first year

Fig. 03 The first year as the tradition keeps it, on a line drawn so that the first month and the whole year both fit. At the birth the bed mother is thanked at the bed. On the third day the child is bathed for the first time before the family, the xi san, with coins and eggs in the water. The first thirty days are the confinement, the month the mother does not leave the house, the room is kept warm and closed and visitors are kept out, which is the tradition’s postnatal ward; it ends at the full month, when the child’s head is shaved, red eggs are sent to the relations and the child is shown to the world with a name. At a hundred days the first feast is given, and at the first birthday the child is set before a tray of objects, a brush, a coin, a seal, a needle, and what it reaches for is read as its life, the choosing test the novels made famous. The rites are the household’s calendar for a new person, and the site’s guide reads the room they were kept in. The rites are the ones Bodde finds in the Han and Knapp in the modern house, and the confinement is the practice Pillsbury described from Taiwan and Hong Kong as doing the month; the days are the traditional ones and vary by region within a week.

The tradition marks the first year off in rites, and they are the household’s calendar for a new person. At the birth the bed mother, the chuang mu, is thanked at the bed in Fujian and Taiwan, as Jordan describes, with a small offering set by the cot; she is the goddess of the bed who guards infants, and the reason the tradition treats a child’s bed as a place and not a piece of furniture. On the third day the child is bathed for the first time before the family, the xi san, with coins and eggs in the water for luck. The full month, man yue, ends the confinement: the child’s head is shaved, red eggs are sent to the relations, the child is shown and given a name, and the mother leaves the room. At a hundred days, bai ri, the first feast is given. At the first birthday the child is set before a tray of objects, a brush, a coin, a seal, a needle, a book, and what it reaches for is read as its life: the choosing test, zhua zhou, which the novels made famous and which every family knows is a game. Bodde finds the third-day and full-month rites in the Han, and Knapp finds them in the modern house; they are the tradition’s way of counting a child into the family by stages, and a household that keeps any of them is keeping the calendar the household gods essay describes.

Design observation · A room that will change three times

A designer plans the baby’s room as the first of three rooms in the same walls. For the first six months it is the parents’ room with a cot in it, and the drawing above is that. From six months to two years it is a room of its own with the cot where the drawing puts it, a floor kept clear and a gate at the door. After that it becomes the children’s room, with a bed in command, a desk by the window and a floor for play, which that page draws. The one thing worth deciding now is the wall: the solid wall the cot stands against is the wall the bed will stand against for the next fifteen years, and the window and the door should be chosen with that in mind. Alexander’s pattern for the bed alcove is the same advice in another vocabulary.

The baby’s room, in order

Before the birth, nothing built. No renovation, no move, no drilling in the room the almanac names; the room made ready in the last month.
The cot against the solid wall. Head to the wall, out of the door’s line, a metre from the window and the radiator, nothing over it.
In the parents’ room, not their bed. For the first six months at least; the cot in view of the pillow.
Not overheated. Warm for the mother in the month if she keeps it, and the child dressed for the room rather than the room heated for the child. The safe-sleep guidance gives no temperature and neither does this list.
Light by the clock. Daylight in the morning, dim and warm at night, no screen in the room.
The chair with a wall behind. In the corner, the door and the cot in view, for the night feeds.
The year marked. The third day, the full month, the hundred days, the first birthday’s tray: the household’s way of counting a child in.
The wall chosen for fifteen years. The cot’s wall is the bed’s wall; pick it with the desk and the window in mind.
