Your baby swallows and tastes amniotic fluid

This week’s developments

Your baby is swallowing and digesting tiny amounts of amniotic fluid now. Their taste buds are developing, which means they’re getting a preview of whatever you’re eating. (No pressure, but it’s a fun reason to savor that ice cream.)

Vernix caseosa, that creamy white coating, is protecting their skin from the amniotic fluid. Some babies are born with traces of it still on. It’s nature’s perfect moisturizer, keeping their delicate skin from getting prune-like.

Movement milestones

• Hiccups. You might feel tiny rhythmic jumps, baby’s diaphragm is practicing for breathing.
• Sucking their thumb. Ultrasound techs often catch them mouthing their hands this week.
• Responding to sounds. Loud noises might startle them (or lull them to sleep).

Their eyebrows and hair are filling in. Whether they’re born with a full head or just peach fuzz depends on genetics, but the follicles are hard at work. Some parents even spot their baby’s hair on the ultrasound now.

Your body at 20 weeks

Halfway there! This milestone comes with some very real aches. Your ligaments are stretching to accommodate your growing uterus, and that familiar round ligament pain might feel sharper now. A warm bath or gentle prenatal yoga can help loosen things up.

Leg cramps wake a lot of parents at night around now. Stretching before bed (point and flex those toes) and staying hydrated can ease them. If they’re relentless, ask your provider about magnesium supplements, many find them helpful.

• Lightheadedness. Your blood volume has nearly doubled, so standing up slowly helps avoid dizzy spells.
• Vivid dreams. Blame the hormones (and maybe the subconscious processing). They’re wild but harmless.
• Linea nigra. That dark line down your belly? Totally normal pigment change. It’ll fade after birth.

On the horizon

The anatomy scan lands here for many. This detailed ultrasound checks baby’s growth, organs, and placenta position. It’s also when some parents choose to learn the sex, if you want to, that is. (No pressure either way.)

You might start feeling kicks more consistently. Early flutters can still be subtle, but some babies make their presence known with proper jabs by now. If you’re not feeling movement yet, don’t panic, especially if it’s your first. Many feel it closer to 22–24 weeks.

Sleep might get trickier. Between a creaky pelvis, heartburn, and general size discomfort, side sleeping with a pillow between your knees becomes your best friend. A pregnancy pillow can help if you haven’t grabbed one yet.

• Ask your provider about the 20-week scan results if they don’t explain them fully
• Start researching childbirth classes, many fill up fast
