Your baby this week
Your baby is getting a wonderful gift from you — your antibodies are crossing through the placenta to protect your baby. This passive immunity will shield your baby in the first months of life until it builds its own. The pupils can detect light and change size. Your baby's coordination is improving — it can grab its toes! The lungs are almost fully mature. Your baby is getting heavier and stronger every day.
Your body this week
You may feel overheated much of the time. Waddling is normal — the wider gait helps you balance. Sleep is challenging; try pillows between your knees, under your belly, and behind your back. Braxton Hicks continue. You might feel anxious about labour and delivery — this is completely normal. Talk about your fears with your partner, a friend, or your doctor.
