do you burp your baby in between the same feed? sometimes, if the baby can't drink as much, it could be due to air in the tummy fr bottle, so you can try burping the baby after she stops the first time, then try feeding again to see if he wants more? personally I find this useful as with this practice, the baby hardly throws up some milk? which sometimes they do if I burp only once, after feed?
as for cries, after some time, one might be able to guess what the baby needs, whether it's due to wet diapers? hunger? warm weather? or discomfort of tummy perhaps? or does the babybwants to be carried? one of girl was so used to being carried and walk around by grandparents for 2 mths every night that when they left and we do not have that practice since we're working, she cries and want the same! she stops when we walk her around at night.
waking up for night feeds are common.it really varies fr baby to baby... my eldest actually wakes up for feed 1.5 hourly last time while another is happy with 3 times a night.
if you are concern, maybe you can check w pediatrician the next time you bring her for jab?
