By the time your baby reaches thirty-two weeks of fetal growth, she will weigh around four pounds. Her senses have really been developing, and all five of them are working properly now. Her fingernails and toenails are fully developed, also. She continues to put on weight and fill out. While not all babies are born with a head full of hair, the hair on her head is continuously growing. She is running out of room in your tummy but continues to be active.
