Your baby this week
You're in the final trimester! Your baby's brain is super active now and can dream. Grooves and folds are forming on the brain surface, building more capacity every day. Your baby sleeps and wakes at regular times, and loves sucking its thumb — it's practice for feeding. The lungs are still maturing, but they're getting closer to being ready. Your baby is safe and cozy in there.
Your body this week
Welcome to the third and final trimester! Excitement and anxiety may mix together — both are completely valid. Shortness of breath continues as your uterus pushes against your diaphragm. Heartburn may intensify. Restless legs syndrome can appear at night. Swelling in feet and hands is common. You're on the home stretch now — the finish line is in sight.
