Nineteen weeks and one day. The NHS counts about 21 weeks to the birth. Today you write the five things you want done by then, and give each a week.

Nineteen weeks and one day. Somewhere around now, the far end of this pregnancy comes into view. Today you write down what you want done before you get there, so it lives on a card instead of in your head at 2 a.m.

Your baby

One large ripe beef tomato on a plain pale wooden table, soft window light.

Around 15.3cm long from head to bottom, about the size of a beef tomato (NHS). Your baby's adult teeth are starting to form, lining up behind the first set (NHS). Teeth that won't show for years are already in the queue. The baby is planning further ahead than you are.

Your body

The NHS describes your baby as putting on weight, "getting ready for the birth in about 21 weeks' time" (NHS). "About" matters there: a normal pregnancy lasts anywhere from 37 to 42 weeks (MedlinePlus), so plan for the early end of that range.

The middle trimester is usually the easier stretch to plan in. The Office on Women's Health says nausea and fatigue usually ease in the second trimester (OWH), though tiredness and sleep problems still sit on the NHS list for this week (NHS). And the calendar gets busier: checkups are monthly until 28 weeks, twice a month from 28 to 36, and weekly from 36 until birth (OWH).

  1. The halfway countdown

    Time: 20 minutes

    1. Write the five things you most want done before the birth. Five, not fifty: the ones you'd regret skipping.

    2. Pencil in the ones that already have a date. Gestational diabetes testing typically happens between 24 and 28 weeks (CDC), and the NHS's list for this week includes thinking about where to give birth (NHS).

    3. Give every other item a week number, spaced out, and leave the last month as empty as you can.

    4. Split the list: each item gets one owner's initials, yours or your partner's.

    Make it work:

    If an item feels urgent and you can't say why, it probably isn't. Move it to week 30 and see whether it still matters then.

Watch for

  • Normal

    a list like this setting off a wave of worry that passes.

    Call your provider

    if anxious or low feelings last and don't lift, or for scary, upsetting thoughts that don't go away; these can be treated (AAP).

  • Normal

    itchy skin as your belly stretches; about 20 percent of pregnant women feel itchy (OWH).

    Call your provider

    for persistent itching without a rash, which may indicate cholestasis (MedlinePlus).

  • Normal

    more trips to the toilet.

    Call your provider

    for pain when you pee, or a change in the smell or colour of your urine, which may signal a bladder infection (MedlinePlus).

For you

There's no rush. Twenty-one weeks is a long time, and almost nothing on anyone's list has to happen this month. The card is for getting things out of your head, not for starting a sprint.

If the list comes out with fifteen items, cross ten off. The AAP's advice has the same shape: a checklist of pre-delivery tasks, done before your ninth month (AAP). Five items, spread over five months, fits easily.

If you're the partner: take at least two items, and the hardest ones. Then do them without a reminder. Being the person who remembers everything is its own kind of tiring.
