My LO is 5 weeks old and was born 8lbs 9oz.
He will not usually take a pacifier... he will suck on it for a minute ravenously, but spit it out and begin crying once he realizes there's no milk.
I'm not sure what reflux would sound like?
I was pumping every 3.5 hrs and getting about 6 oz each time.
Sleeping 5 hours at a strech for a breastfed baby at 5 weeks old is pretty unusual. It is really normal for a EBF baby to feed almost constantly at this point at not sleep for more than about 2 hours at a stretch, particularly at the age you are talking about right now....there is a significant growth spurt around 6 weeks of age. It's also really normal for a little baby not to sleep soundly flat in a crib because it is such a foreign position to them. You said he sleeps in the swing. What about a chair or a sling, that would help him stay cozy and upright. My DS didn't sleep in the crib at all until he was about 4 months old and my best friend's daughter wouldn't sleep in her crib until almost 8 months. It's not unusual. It's actually pretty common.Rooting and sucking are reflexes for a newborn. If a baby in on the breast, they can comfort suck and not draw milk. If your DS doesnt have that option, I agree with PP that a pacifier might make a world of difference. For us, I EBF'd and still used a pacifier becasue my DS would have sucked my nipples off without it. Seriously. FYI--we had to try 4 different paci's to find one he liked.
WHen you say your baby didn't sleep in the crib for the first 4 months, where did you have him/her sleep?
