Dd2 is 12 days old and for the most part the first 10 days of Bf'ing were pretty good. Dd was attaching without my assistance, feeding every 3 hours during the day and approx 4 hours at night. On Monday night DD fed at 6pm and then I went to bed about 9.30pm expecting her to wake me around 10-10.30pm. To my shock she didn't wake me till 1am and I was FULL!! She fed at 1am then 5am, 8am, 11am, 1.45pm etc.
Yesterday I woke to my breasts not feeling as full as they had been. DD also started to fuss at the breast which she had not done before. She had 6 feeds across Monday and 7 on Tuesday but was quite unsettled.
Today we had apt with paed as DD has a heart murmur and when he weighed her she is now under her discharge weight. She was 3120g at birth, 2965g at discharge and today was 2910g.
He has suggested I BF for 20 mins then comp feed with either EBM or formula. DD falls asleep on the breast within a few minutes most times so I don't think she is draining me. Her first comp she took 40ml of formula and 10ml EBM. Second comp on 15ml formula and 10ml EBM.
I cried while giving her the formula as I thought feeding was going so well and now feel so confused as to what happened to my milk.
Paed gave me a script for Motillium and I have to take her back in a week to be weighed again. I know she needs to gain weight but I'm so disappointed and don't think that she will go back to Bf'ing once she has formula. I was disappointed to only Bf DD1 for about 6 or so weeks but this is even worse.
Any suggestions on why this happened and how I can fix it would be most welcomed.
