Third trimester

Week 29

11 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

Bones fully formed, still soft

About 39 cm. Baby is gaining weight rapidly — fat layers smooth out the wrinkly look.

Body

What's changing in you

Kick counts, gently

Most providers introduce kick-count awareness around now. Patterns matter more than absolute numbers.

Source: Williams Obstetrics, 26th ed. (Cunningham et al., 2022)

Brain

Maternal brain

Nervous system on high alert

Hyperarousal in T3 is partly hormonal, partly evolutionary. Co-regulation matters more than self-regulation now.

Bond

You & baby

Same songs, same times

Predictable input now becomes recognizable input later — a gift to the newborn.

Source: Partanen et al., PNAS 110(37), 2013 — Prenatal experience and learning of melodies

Partner

For your partner

Take over one daily logistics task

Insurance, hospital bag, pediatrician research. One thing — fully. Cognitive load is invisible labor.

Source: Cowan & Cowan, When Partners Become Parents (1992; 2nd ed. 2000)

Movement

Move with care

Pelvic mobility on a ball

Daily birth-ball sitting and slow circles can ease pelvic tension and support positioning (Spinning Babies framework, evidence still emerging).

Nutrition

Eat for two brains

Smaller, more frequent meals

Less reflux, more steady energy. Big meals press on a crowded stomach.

Reflection

60-second prompt

Where do you feel most held?

Person, place, practice. Lean toward it on purpose.
