Your Baby's Development
Your baby already weighs about 5 pounds, 5 ounces (2,400 grams), but this week begins your baby's most rapid period of weight gain — about 8 to 12 ounces (226 to 340 grams) each week! Fat is being deposited all over your baby's body, especially around the shoulders.
Because of this increasing size, your baby is now cramped and restricted inside the uterus — so fetal movements may decrease, but they may be stronger and more forceful. If your baby is in a headfirst position, his or her head will rest on your pubic bone in preparation for labor.
The bond you may already feel with the baby growing inside of you will only grow stronger once your baby is born. Bonding — the intense attachment that develops between you and your baby — is not something that only occurs within minutes or days after birth. It may happen later and it may develop over time. Bonding not only makes you want to protect your baby and shower him or her with affection, but it also fosters your baby's sense of security in the world outside your womb.
