No need to worry....feeding must be on demand

You should awake her after 4-5 hrs of feeding and feed her and burp her well after each feed.

Few things you can monitor, 1 ) urine output, child should passed atleast 4-5 times urine in 24 hours or should passed urine atleast in 6 hours. If child is not passed urine in last 6 hours, give breastfeed feed and look for urine if not passed in 30-45 min you should consult pediatrician. 2) weight gain: if child is gaining weight and adequately then no need to worry. 3) development : if child grows well no need to worry. 4) frequency of feed: child should take atleast 6-7 times adequate feeding in 24 hours. If it is less then wake up child and give feeding
