You are doing well to keep going xx
I was going to say that maybe having a sling might help. I never learned to feed my kids properly in the sling, but being near me was enough for DS2 and he was far more settled when he was at least 'beside' my breasts, if he couldn't be feeding.

Have you talked to someone about feeding a toungue tie?

I doubt that you need to worry about her lack of interest in the big wide world. She's got 2 brothers who are going to help her out there! There's plenty of time for that soon.
