Week 9

Your Baby

How big is my baby?

At the start of week 9 your baby is approximately 22-30mm (0.9 - 1.2 inches) from crown to rump.
Your baby's neck region is becoming more defined and developed, enabling lifting and turning of the now rounded head. The eyes are still forming, and while tiny, they are now covered by eyelids (they were exposed until this stage). The eyes will then remain closed for a large part of your pregnancy. Tiny external ears are still forming and are visible. The nasal passages are opened this week, and the tongue starts to form (although the mouth is still just a flat line on the surface). Your baby's organs are also forming.
