My DD2 is 12 weeks old, and BF very well. She only feeds four times a day, sometimes 5 (DD1 was the same, not a very hungry baby), usually 6am, 12pm, 4pm, 8pm.
I sometimes give her a bottle of EBM, and if so, I then used to express or I would get full, sore boobs and leak. When I expresed after not feeding her, I could easily get 6oz out in ten mins or so.
The last 2 times I have tried to express (having not done so for a few weeks, since she's been on fewer feeds) I have been barely able to get half an oz !!
Therefore, I'm a just a bit worried that my supply is dwindling. DD2 is a VERY content baby, gaining very good weight (today she was mistaken for being 9 months old and she's not even 3 mths!!) and regularly sleeps thru the night from 8pm-6 or 7am. (Her sister did exactly the same!). During the day she happily goes at least 4, sometimes up to 6 hours in between feeds.
Should I be worried about my supply??
