my 4 month baby girl sleeps around 2 in the mid night and wakes up at 9.30 am ...in between she wakes up only when she's hungry...till 2 o clock she plays n sleep for a while . how can I make her sleep early ( I.e. at night) ...are there any tips or routine changes that will make her establish proper day- night sleep cycle?

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 and if the baby is comfortable with no irritability because of infantile colic nasal blockage any regurgitagtion etc yjjou should not worry just give a comfortable position to the baby and no medicine is required.
