I have a 7 day old son who has been dropping weight rapidly. I have him nursing anywhere from 15 to 30 minutes on a side at a time and then I still need to give him 2 oz of formula or he won't sleep. He had a lot of trouble latching on and now that we have worked out, I feel like I have zero milk supply. I have been trying to pump in between feedings to stimulate production. He is soiling 14 diapers a day so I am concerned. I have been keeping a log for the pediatrician of all input and output too. I know that it will take more time to get coordinated but am feeling so weepy like I am failing him.
