So I’m a little worried past two nights my baby has been sleeping from 5-6 hours without waking up.. I know I should be happy bc I get sleep but it’s so weird bc before she would wake up every hour or every 30 mins now she sleeps longer & she’s only a month old. Last night she slept from 11:30-4:45am.. night before was 11-5:30 right before bed she gets extremely fussy too!
That's a great start! If you're worried, talk to your doctor. I had the same concern when my baby slept that long around the same time, and he assured me it was great and to enjoy the sleep. Baby's tummy is getting large enough to not get hungry as often so that may be why.
