Twenty weeks and five days. There's no magic number of kicks; what matters is a change. Today you start learning when your baby is usually busiest.

Twenty weeks and five days. Every baby has their own rhythm, and you're the only person in a position to learn it. Today you start, with a one-minute note each evening.

Your baby

A single yellow banana on a plain white linen cloth, soft daylight.

Around 25.6cm long from head to heel, about the size of a banana (NHS). Over the next week or so, the NHS says your baby will be moving around a lot and establishing waking and sleeping patterns (NHS).

Your body

A woman may begin to feel her baby move at 20 weeks (NICHD), and many first notice it between 18 and 24 weeks (NHS). Babies often move more after you eat, during loud music, and while you relax (NHS).

Here is the fact about movement worth keeping. The CDC says there is no specific number of movements that counts as normal; a change in movement is what matters (CDC). Which means the comparison is never your baby against someone else's. It's your baby this week against your baby last week. To notice a change, you first need to know the usual.

Try today

  1. The movement baseline

    Time: 1 minute each evening, for a week

    1. Each evening, write down when you felt the baby most today: morning, afternoon, evening, or night (NHS).

    2. Add what you were doing: just eaten, lying down, music on (NHS).

    3. At the end of the week, circle the busiest time of day. That's your first baseline.

    4. Feeling little or nothing yet? Write "nothing yet" and keep going; the log starts working whenever the movements do.

    Make it work:

    Keep it in the same place every night, a paper diary by the bed or one note on your phone. A week of one-word entries is plenty.

Watch for

  • Normal

    quiet days and busy days, especially this early, while movements are still new (NHS).

    Seek care immediately

    later on if your baby's movement stops or slows once you know their pattern (CDC); the NHS says to talk to your midwife if the kicking slows (NHS).

  • Normal

    round ligament pains as your bump grows (NHS).

    Call your provider

    or go to the hospital for pressure in your pelvis or hip area, or cramps like a period; both can be signs of preterm labor (NICHD).

  • Normal

    reading a list like this and recognising nothing on it.

    Call your provider

    if you feel like something just isn't right, even if it isn't on any list; the CDC asks you to make the call anyway (CDC).

For you

You're not counting yet. Formal counting starts at 28 weeks, when the Office on Women's Health says most women count 10 movements in about 20 minutes (OWH). This week is just getting to know the person in there, the way you'd learn a new housemate's hours.

You will also learn to trust yourself here. Nobody else can feel what you feel. If your gut says "this is different," that's information, and your provider would rather hear it than not.

If you're the partner: ask her each evening, "When was the baby busiest today?" Then write the answer for her. It makes the log a habit for two.
