DAVE & CARRIE'S OLDEST DAUGHTER: BRITTANY Dаve аnd Cаrrie’s оldest daughter, Brittany (age 23, height 5'5", weight 130 pоunds befоre pregnancy) is 4 months pregnant with their first baby. She doesn’t want to get too fat, so she thinks a 10-12 pound gain should be enough for a healthy 6-7 pound baby. Brittany plans to use iron-fortified formula to feed her baby, since she will have to go back to work right away. Besides, Nelson thinks breast feeding is weird. She wants her baby to sleep through the night as soon as possible, so she expects to start feeding him a wide variety of commercial baby foods starting when he is about 3 months old. Nelson loved family dinners every day when he was growing up, so he has been trying to convince Brittany that they should establish a tradition of family meals together.
