Forty-two weeks: the bottle wind-down begins

Last reviewed · 4 min read · 8 sources · Plain-text version

Bottles end between 12 and 18 months, so the first one goes now: keep the mealtime bottles, drop a nap or bedtime one, add cuddles and a story. Never a bottle in bed. The first bottle to go.

An East Asian mother in a dim nursery at bedtime reading a board book to her forty-two-week-old on her lap, a cup of milk on the dresser behind instead of a bottle, the father leaning in the doorway.

Forty-two weeks. Three weeks ago you drew the bottle map. Today one bottle comes off it, and the thing that replaces it isn't a cup. It's you.

Heart

The AAP suggests offering a cup around 6 months and finishing the move off bottles sometime between 12 and 18 months (Shu, AAP). The window opens in about two months, so this is the time to start. The order is the AAP's: cut bottles gradually, keep the ones at meals at first, drop the ones at naps and bedtime, and offer extra cuddles and stories instead (Shu, AAP). The milk doesn't go anywhere; breast milk or formula is still the main drink until the birthday (Muth, AAP). What changes is the one bottle that was really about sleep.

Head

Bottles that go on longer are linked to cavities, skipped meals, and more resistance later (Shu, AAP). A bottle in bed is its own problem at any age: sugary residue left in the mouth overnight promotes tooth decay (AAP), and if teeth are in, the brushing comes after the last drink or food of the day, not before the bottle (AAP). None of it is urgent this week; all of it is easier at ten months than at eighteen.

Body

The replacement is a routine, and the AAP's version is Brush, Book, Bed at a regular bedtime (AAP); in a survey of mothers of 10,085 young children, more consistent routines went with better sleep, though a survey can't prove cause (Mindell et al., 2015). The guide's shape is a bath, then stories or songs, then down drowsy but awake (Nemours KidsHealth). If the bedtime bottle was the last step, the story becomes the last step, and the milk moves earlier, to the table. The guide's section is Cups in, bottles out.

Try today

  1. The kitchen counter in morning light: three bottles in a row and one straw cup, the mother's hand moving a fourth bottle into a cupboard, the baby in the high chair with the harness on watching.

    The first bottle to go

    Time: One decision today, then a week · Cups in, bottles out in the guide

    1. Look at the bottle map, or make one now: every bottle of the day and when it happens. Circle the nap bottles and the bedtime one; the mealtime ones stay for now (Shu, AAP).

    2. Pick one circled bottle, the easiest, and write the date next to it. That's the one that goes this week.

    3. Move its milk to the meal before it, in the bottle or a cup; the amount stays the same (Muth, AAP).

    4. In its old slot, put a longer cuddle and one more book, the same book each time (Shu, AAP).

    5. Seven days, same slot, same book. Then look at the map again and circle the next one.

    Make it work:

    Every caregiver gets the map. The bottle that comes back on the sitter's day is the one that never leaves.

Watch for

  • Normal

    a loud week in the slot where the nap bottle used to be, and a baby who sleeps anyway.

    Talk with your pediatrician

    before cutting feeds if your baby isn't growing and gaining weight steadily (AAP).

  • Normal

    a baby who bites the cup rim with new teeth; plan the first dental visit after the first tooth and by the first birthday (AAP).

    Call your pediatrician right away

    for a fever over 104°F (40°C) (AAP).

  • Normal

    a rough first night when the story replaces the bottle, better by the third.

    Go to the ER now

    if your baby is hard to wake, isn't alert when awake, or seems confused (AAP).

For you

The mother and father on the sofa after bedtime with the baby monitor between them, a calendar page on the coffee table with one bottle drawn and crossed out, both looking tired and pleased.

A plan, not a fight. The AAP's window, 12 to 18 months (Shu, AAP), means nothing has to be finished this month, and the first bottle to go is allowed to be the one nobody will miss. If you're breastfeeding, none of this is about you: the AAP supports continuing as long as you both want, to 2 years or beyond (Muth, AAP), and the bottle wind-down is for the bottles, whatever is in them. The cuddle and the story that replace a bottle are ten minutes at the end of the day with a warm, heavy baby and a book. Take them as yours.

If you're the partner: the bottle that goes first is the one you'll be in the room for. The book is in your voice this week, so the swap is tied to you and not to the missing bottle.
