Your baby weighs around 8–9 ounces (250 grams) and is about 6 inches (22 cm) long. She is covered in vernix caseosa, a white and waxy substance, that protects her fragile skin from becoming chapped or scratched. Permanent teeth buds are also forming behind the already formed milk, or baby, teeth buds.
If your baby is a girl, her ovaries also contain primitive egg cells. Girls are born with all the eggs that they will have in their life. She is also developing more brown fat around the neck, chest and crotch. Brown fat will keep your baby warm from the time she is born until her body is able to regulate its own temperature. She also might start sleeping this week. Babies can find a “favorite” position. Usually, babies will have their chin tucked into the chest. Most babies can even dream (REM sleep)!
