PZ I remember thinking I couldn't be breastfeeding right because DS was such an efficient feeder. We had 5-10min feeds from birth, i remember asking the MCHN when she came to visit me at home on day 5 and she said just to enjoy it! It is probably the only reason I was able to stick it out with breastfeeding because most of the time I really disliked it.
Im a bit scared that this time won't be so easy (and its a miracle i had it easy last time so i dont expect it) and Ill give up.

As for the sleeping, yep that all sounds about normal - she may be having a growth spurt as well with the additional sleeps and less output - and I second Trish about the baby body efficiency of using BM - especially if she is growing.

You are doing great xX
