In utero, baby ll sleep during daytime, awake during night time..same thing continue for 1 month after delivery.. use very dim light during night..try a gap of atleast 2 hrs in between feeds..for few days, it ll be difficult..then baby ll adapt to it...if continuously crying for more than 30 min, not able to console, then ll try medicines..

Follow proper breast feeding norms. Feed the baby one breast at a time for at least 15 - 20 min. Burp her properly. If need be you can give colic - aid drops -8-10 drops.

May be baby is not getting  enough milk ....try giving top feeds. Continuous feeding causes indigestion and gasses. Feed properly... Usually once fed baby will not be hungry  for about 2 hrs ....burp baby by holding straight on shoulder for about 10 - 15 min after feeds.
