My dd just had her 4 month check up and is 12 #. She had a little dip in her growth curve. She used to be between the 25th and 50th and now she is between the 10th and 25th. The dr. isn't worried, he said I just just don't want it to dip further. She hasn't gained any weight in the past 3 weeks-about 1-2 ounces. She feeds every 4 hrs, with a feed at 1030 and usually at 130. I top her off with 2-3 oz. at her7 pm feed. She seems content and happy. Am I overrreacting? Is this common for Bf babies?
