Your Baby's Development
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. The vernix coating on the baby's skin is becoming thicker, whereas lanugo hair is almost completely gone.
This increasing size means that your baby is now cramped and restricted inside the uterus — you might feel fewer movements, but they may be stronger and more forceful. If in a headfirst position, your baby's head will rest on your pubic bone in preparation for labor.
Your bond with your baby will be even stronger once your little one is here. Bonding doesn't only happen right after birth. It may happen later or develop over time. Bonding makes parents want to protect their baby and shower him or her with affection, and it builds a baby's sense of security.
