I've been ebf my 12 week old daughter and all seemed to be going well: she's happy and alert, and breastfeeding fairly frequently during the day for up to an hour at a time. At night she can sleep 4-7hours before a feed. I had noticed when I tried to express though, I was getting very little: maybe half an ounce per session which made me wonder how good my supply is. (I gave up trying to express as with her long frequent daytime feeds, it was really making it impossible to ever get out of the house.). Often during the afternoon and evening my breasts feel soft and empty. Yesterday I took her to the local breastfeeding group for a weight check and it turns out she's now between the 9th and 25th centile, having been born on the 50th. Should I be worried about my supply? And if so,,what can I do about it? I really don't want to have to give formula top ups and she really is a happy settled baby. Thanks.
