Your baby this week
Your baby is now about the size of a cabbage, and the soft hair that has covered the body is beginning to shed in preparation for birth. The brain is developing quickly, growing more able to process information, while the bone marrow takes over producing red blood cells. Your baby can now recognize sounds and may respond to gentle music or the loving tone of your voice.
Your body this week
You may feel more tired and heavier on your feet as your due date approaches, along with some mood swings. It's also common to feel pressure on your bladder with more frequent trips to the bathroom, as well as passing Braxton Hicks contractions.
Tips for this week
Give yourself time to rest and unwind, and don't hesitate to ask for help with everyday tasks. Talk about your feelings with your partner or someone you trust, because emotional support matters just as much as physical rest. If you feel persistently low or weighed down by worry, sharing that with your doctor is a kind step toward your well-being.
