Cali you are not a failure! You created this little girl, she is just getting used to the outside world. It used to be warm and snug with a reassuring heartbeat and swaying action.
I had major issues with breastfeeding but here's a few tips that might help:
Is Abigail having frequent wet nappies? If so, she's feeding fine. My DD had very dry cracked lips, didn't catch on this would be dehydration
Are you winding her after every feed. Trapped wind was the main cause of grumpiness for us. I used to go for a walk over gravel/bumpy surface and it always helped move her wind.
Before getting DD to latch on, can you express. Couple drops of colostrum/milk to intice her to latch on.
If I couldn't calm down DD after a feed, I gave her to DH to settle. DD couldn't settle on me whilst breastfeeding/expressing as she could smell milk. DH cuddled soothed and I sang lullabies to settle her.
Has your milk come in yet? My baby blues kicked in at this point and oh my, did I cry at everything. ESP that I couldn't breastfeed and felt a failure. Awful time for me so I am holding your hand as I know what it's like. You are doing wonderfully.
Hopefully someone with more experience in breastfeeding will have better advice. Just didn't want to ignore your post. We are here for support ante or post natal support x
