Different babies have different appetites but the cues are mostly the same. You'll see them kindof rooting (searching for a nipple) and they'll put their lil fists in their mouth to suck. Those are the non-crying signs I watched for.
My son was a sleepyhead and mainly wanted to sleep while we were in the hospital. The nurses kept stealing him away from me so he'd be in the nursery. I was throughly disgusted with them! How was I supposed to breastfeed him when they snatched him away from me every 10-15 minutes!??
They then proceeded to FUSS at me because he wasn't eating enough! Needless to say, once we were home, and on my son's schedule instead of their paperwork/diaper weighing schedule, things got better.
He was a vaginal delivery, he latched right away. Never had any issues with soreness or breastfeeding other than the darn nurses there at the hospital. I do remember he was a sleepy baby and when I was lucky, he'd feed for 10-20 minutes at a time before passing out.
My daughter was a c-section delivery. I wasn't able to hold her right away (not until 4-5 hours after her birth) but she still wasn't interested in eating by the time I held her. That night though was a completely different story. She wanted to nurse pretty much nonstop ALL night long (sometimes she'd sleep for 10-15min before wanting to nurse for another 10-20min
) and she had a supershallow latch which was quite painful
I think because she was so small, she just couldn't open her mouth wide enough to take in as much as she was supposed to. My milk came in super fast though, by the end of the second day. By the time she was a couple weeks old, her latch got better (practice makes perfect but in the meantime it was a toecurling experience
).
Hang in there! The first 2-3 months are the toughest. Don't let youself by psyched out by not knowing how much baby is getting when he/she nurses. As long as you have output (dirty diapers) you know baby's getting input
