Maryanne, a 23-year-old mother of two children, is at the clinic for their checkup. Zachary is 7 months old and Lucia is 18 months old. Zachary weighed 8 lbs 4 oz at birth and now weighs 18 lbs. Lucia weighed 7 lbs 10 oz at birth and now weighs 20 lbs. When the nurse commented on the weight of both children, Maryanne said that she was small and petite like Lucia when she was a child
? Further discussion revealed that Maryanne was breastfeeding Lucia when she found out she was pregnant again. The pregnancy was confirmed when Lucia was 2 months old, and at that time she stopped breastfeeding. She had a difficult time converting Lucia to a bottle and she says she just began to feed her more solid food than the bottle. Lucia seems to be withdrawn from the situation. She is sitting quietly at a small table, virtually ignoring all of the activities in the room, and playing with an infant rattle. Her mother says Lucia "is the best baby because she plays for hours in her room by herself." She says that at one time she was concerned because Lucia was so slow in learning to walk. "After she learned to walk at 16 months, she seemed to do much better and became more active." ? When Maryanne was questioned about her support system, she stated that her husband left when he found out she was pregnant with Zachary. Her parents are both dead and her only relative is an elderly aunt who is in a nursing home. She says she visits her aunt as much as she can with the two children. The physician has made a diagnosis of failure to thrive. The mother does not understand why the nurse and the doctor are so concerned about Lucia's weight. Tell Maryanne about the usual weight gain of infants.
