Your babys progress - Week 13
Baby’s head is still whopping and large in comparison to her growing body, but her nose and chin are now well-defined and bones like the ribs are forming. From this point on, baby’s body starts growing to catch up with that big head, and baby is likely to be around 7cm to 9cm and will enjoy sloshing around in 100mls or so of amniotic fluid.
Baby’s hands can now start wondering and studies have shown babies like to explore and touch their own face. Some babies suck their thumb in the womb, and others just make a sucking action with their mouth. Your baby now has a gag reflex, too. Your baby can move in a jerky fashion, flexing the arms and kicking the legs. In fact, if you prod your abdomen, your baby will squirm in response, although you won't be able to feel it just yet.
The first three months from conception were period of rapid development, and the ensuing three months will be a period of rapid growth for your baby. Her skin is paper-thin and rather see-through, and if you could see her inside you, you could even get a glimpse through her skin of her functioning and still-developing organs.
Baby’s sense of taste and smell are more developed and her amniotic sac will continue to increase in size and mass and fill with more fluid. Baby had better enjoy all that space she’s got right now for somersaults and movement because in another few months it will get squishy!
Just like adults, all babies are different and develop at varying rates in the womb. This information gives a general idea of your baby's development and progress.
