I had my 3rd baby a week ago, he weighed 9lbs 15oz and I am exclusively breastfeeding. He is my first I have managed to feed myself as I had problems with the other 2. Yesterday he was weighed and I was told he has lost a little over 10% of his weight and they want him weighing again tomorrow. This has really got me worried now, I feed on demand and he's having plenty of dirty and wet nappies in the day and night. I have no experience of this because my other 2 were mainly formula fed they didn't lose much weight. It's got me really worked up that they will think I am not feeding him. I hope someone can tell me I don't have anything to worry about. I just really don't want to have to supplement with formula when I have done so well to keep breastfeeding.
