Hi, this is my first time to post a question about a challenging case and am hoping someone can help. I have a mother who is breastfeeding exclusively a two month old. . The baby nurses every 2-3 hours for 10-15 minutes each side and seems satisfied. The baby weighed 8-14 at birth and now weighs 18 pounds and 14 ounces. The only thing that she has reported is that the baby wheezes for a short time in the morning and the evening but is fine during the day and at night. Mom denies congestion or any other symptoms when the wheezes occur. Her pedi told her that the weight gain was way too much and could be causing problems. She wants her to eliminate a breastfeeding and subsitute it with a water feeding. The pedi also said that she wants to a Upper GI and a chest xray to rule out a shift of the trachea to the right. I am perplexed by this, don't know enough about excessive weight gain, I have tried to look up but resources deal with poor weight gain. There is mention that breastfed babies do gain faster initially but then level off although this baby's weight gain does seem like alot. However the family is a tall big family not really overweight but husky. The baby is off the chart for the head and weight and the height is at least 100 percentile. The mom doesn't want to eliminate one feeding doesn't feel that baby will go for it. Does anyone have any information about excessive weight gain? Has anyone ever heard of weight gain causing a trachea shift to the right? Has anyone out there seen this type of weight gain ? Causes or management of it? I would be grateful for any information. TIA.
