Third trimester

Week 31

9 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

Senses integrating

All five senses functional. Baby may startle at a sudden touch on the belly.

Body

What's changing in you

Sleep gets harder

Hip pressure, reflux, peeing. Side-lying with a pillow between knees and one under the belly is the most-tested setup.

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

Brain

Maternal brain

Dreams become more vivid

T3 sleep architecture changes — more wake time at night means more dream recall, not necessarily worse sleep.

Source: Mirmiran, Maas & Ariagno, Sleep Medicine Reviews 7(4), 2003 — Fetal & neonatal sleep

Bond

You & baby

Slow exhales when baby moves

Long exhales activate the vagal brake; you co-regulate baby's nervous system through your own.

Source: Porges, The Polyvagal Theory (2011) — Co-regulation & autonomic safety

Partner

For your partner

Massage the calves

Cramps and swelling are common in T3. A nightly five-minute calf massage is worth more than it sounds.

Movement

Move with care

Hip-mobility nightly

Cat-cow, child's pose with wide knees, modified pigeon — three minutes before bed (Bø 2016).

General info — not personalized medical advice.

Nutrition

Eat for two brains

Salt to taste

T3 needs more sodium, not less, in the absence of hypertension. Don't under-salt.

Reflection

60-second prompt

What would 'easier' mean tonight?

Name it. Choose one thing. Do less.
