my 4 months old baby girl does not sleep at night .she is all awake whole night,sleeps in the morning.

A. Sleep Cycle in smaller babies is very different and they have a certain pattern initially which becomes regularize at around 6 to 8 months of age agynd if the baby is comfortable with no irritability because of infantile colic nasal blockage any regurgitation etc you should not worjry just give a comfortable position to the baby and no medicine is required.
