Week 38

2 weeks to go

Eight short cards a week — the baby, your body, and you. You can read them in ten minutes and close the app.

Baby

What's growing

Full-term territory soon

About 49 cm, ~3 kg. Full-term begins at 39+0. Brain growth continues at full pace.

Body

What's changing in you

Cervical changes invisible

Effacement and dilation may be happening quietly. Cervical checks predict little — many people walk around at 3 cm for weeks.

Brain

Maternal brain

Decision fatigue is real now

Reduce non-birth choices. Eat the same breakfast. Wear the same outfit. Save bandwidth.

Bond

You & baby

Sing the lullaby you've chosen

If you have one — sing it daily. It will be the soundtrack of soothing for years.

Partner

For your partner

Run the bag check

Phone chargers, snacks, ID, going-home outfit, car seat installed. Out loud, together.

Reflection

60-second prompt

What would you tell your past self?

Three weeks ago, three months ago. Then say it to yourself now.
