21 Weeks Pregnant: What To Expect, Baby Development & Doula Tips

Are you 21 weeks pregnant and feeling all the feelings? Let’s talk about it!

As a doula and lactation consultant, I love walking alongside first-time moms through every beautiful (and sometimes weird) part of pregnancy. And week 21? This is such an exciting milestone!

Here’s what’s happening inside your body — and what to expect from your baby right now.

Baby Development at 21 Weeks Pregnant

• Baby is about 10.5 inches long — about the size of a banana!

• They’re swallowing amniotic fluid (and tasting what you eat!)

• Baby’s digestive system is practicing for life outside the womb

• Movements may feel stronger & more rhythmic now

• Tiny eyebrows, eyelashes & facial features are becoming more defined

Common Symptoms at 21 Weeks Pregnant

• Round ligament pain (ouch!)

• Stretching belly & itchy skin

• Trouble sleeping

• Braxton Hicks contractions (practice contractions!)

• Increased hunger — your baby is growing fast!

Doula Tips For 21 Weeks Pregnant

→ Hydrate like crazy (amniotic fluid replenishes daily!)
→ Nourish with protein & healthy fats to support baby’s growth
→ Use belly oil or lotion for itchy skin
→ Start practicing daily relaxation or breathing exercises
→ Begin learning about breastfeeding NOW (yes, before birth!)

What Most Moms Don’t Realize About Week 21

→ Your baby is already responding to sounds, especially your voice!
→ This is a great time to start creating calming routines like talking or reading to your belly.
