23 weeks

Your baby is now about 8.4 inches from crown to rump (21cm) and weighs about 1.2 pounds (530g).

Your baby's face and body now look more like a full-term baby. She now looks close to how she will look at birth.

The eyes, though they are still closed, are now close together on the front of the face and the ears are in their finished position. Eyelashes are fairly well-developed and hair is growing on your baby's head.

Your baby's movements are becoming more restricted now as she fills up the uterus more. Cartwheels and somersaults inside the amniotic sac are no longer possible, but she can still hold the umbilical cord and touch and feel around her. Though your baby is already living in tight quarters in the amniotic sac, she will soon have even less room to move around.

Her vital organs are now quite mature. However, since the lungs are not yet fully formed, your baby would have breathing problems if born prematurely at this stage.

Your baby is becoming increasingly conscious of the world outside and may feel startled when you are startled.

Your baby may alternate between having very active and very calm periods that you can feel.

Your baby may have facial expressions such as frowning, squinting and pursing of the lips.

This is cool, how the baby becomes aware of its environment. Heidi has been able to tell for a few weeks now when Crazy Legs is "active", i.e. practicing for the Olympic floor routine with flips and somersaults.

Seems I'm always across the room when Heidi suddenly goes "Whoo! Baby's moving!" and when I rush over, I feel absolutely nothing. The kid's gonna be a great hide-and-seeker, and is already excelling at making Dad feel foolish.
