Baby is now the size of a large cabbage

For many parents, this milestone feels both exciting and surprising — the positive test may feel like yesterday, yet your baby is now a growing little person who can hear, move, stretch, hiccup, and respond to the world around them.

Frequently asked questions
Is it normal for movements to feel different?
Yes. As your baby grows larger, movements often feel more like stretches and rolls rather than big flips.
Why do I feel so much pelvic pressure?
Your growing baby, uterus, and changing posture place additional pressure on the pelvis.
Is nesting real?
Many parents experience a strong desire to organize and prepare for the baby's arrival during the third trimester.
Should I have my hospital bag packed yet?
You do not necessarily need it packed this week, but many parents begin planning and gathering items around this stage.
