Welcome to Week 21! As you move further into your second trimester, you might be noticing some significant shifts, both with your baby's activity and in your own body. This week, your baby is often compared to the size of a carrot, measuring around 267mm. It's a time of continued growth and development, and for many, a period where the pregnancy feels increasingly real and tangible.
What's happening with baby
At 21 weeks, your baby is becoming more and more active, and their movements are likely feeling stronger and more distinct. They're practicing important reflexes like sucking and swallowing, and their taste buds are developing, allowing them to experience flavors from the amniotic fluid. Their skin is still thin and translucent, but fat deposits are beginning to form, which will help with temperature regulation after birth. Sleep and wake cycles are also becoming more established, though they might not align with yours just yet! Organs continue to mature, and the nervous system is refining its connections, paving the way for more coordinated movements.
What you might be feeling
For many, Week 21 marks the beginning of more rapid weight gain, which is a natural and healthy part of supporting your baby's growth. You might notice your center of gravity shifting, leading to changes in posture. The stronger baby movements, often called 'quickening' when they first appear, are likely now more consistent and perhaps even visible from the outside. This can be a truly joyful and connecting experience. You might also continue to experience some common pregnancy symptoms like heartburn, swelling in your feet or ankles, or occasional leg cramps. Emotionally, many parents-to-be feel a growing sense of anticipation and connection, as the reality of meeting their baby draws closer.
