Your baby at 31 weeks

31–32 weeks

The baby grows like a leaven: its weight is already over 3.3 lb, the amount of fat and muscle is constantly increasing. The less space he has for activities, the more he listens to an exciting world outside and reacts to everything he hears. Therefore, make sure that he hears mostly pleasant things (the baby is brainy already, you never know what, maybe he will suddenly remember something...) And just imagine — your sweety has grown long nails and now can get himself into the eye (do not worry, if nail touches the eye cornea, the baby will immediately blink). It is a pity that you cannot protect him from himself yet, so distract him, talk to him, appeal to accuracy and prudence.

It's only here, in the pic, that we decided to show you your baby traditionally, head — body — legs. But in fact, he has already turned his head down, and in this bat position, he patiently waits when he can explore that external fantastic world. By the way, for the reason of future birth, the skull is still soft, although rest of the bones have already become firm: to facilitate passage through the birth canal to both the baby and Mommy. And while he waits, he doesn’t waste time: just like ill-bred babies in the pool, he releases about 0.5 liters of urine into the surrounding amniotic liquid every day.
