Pregnancy week 20
This week your baby is about the size of a banana — around 16.5 cm and 300 g.
Your baby this week
You've reached the halfway point, and your baby is growing steadily and swallowing small amounts of fluid, useful practice for the digestive system. The intestines are producing a first substance called meconium, which will become baby's first stool after birth. Fingernails are nearly complete, and your little one can hear your heartbeat and voice more clearly now. Taste buds are also developing on the tongue.
Your body this week
Your belly is more prominent now, and you may feel your baby's movements more clearly. Heartburn or indigestion are common as your uterus presses on your stomach. You might also notice a faster heartbeat, since your body is pumping more blood to support you both.
Tips for this week
Eat small, frequent meals and avoid lying down right after eating to ease heartburn. This is a lovely moment to take a keepsake bump photo, since the halfway mark is worth celebrating. Keep noticing your baby's movements, and if you later feel a marked change in them, contact your doctor.
