Baby is now the size of a avocado
Welcome to Week 16. For many parents, this is one of the most exciting weeks of pregnancy. Some mothers may begin feeling the first tiny movements from their baby, often described as fluttering, bubbling, or gentle taps. Your baby is growing quickly, becoming stronger, and developing more control over their movements. The second trimester is often in full swing now, bringing more energy and fewer symptoms for many women.

Frequently asked questions
Can I feel the baby moving yet?
Some mothers can. Early movements often feel like tiny flutters or bubbles. First-time mothers may not notice them until a few weeks later.
Is it normal not to feel movement yet?
Absolutely. Many first-time mothers do not feel movement until Weeks 18 to 22.
