my daughter is 1.5 month old she is not sleeping at night she sleeps on my lap,bt when I put her in bed she woke up she sleeps whole day how I change her routine

Baby at this age needs to eat every two to three hours and hence will awaken a couple of times at night. You can help her sleep better in the night by keeping day time noisy and bright and awakening her regularly for feeds and night can be quiet and dark. Put her down and Pat her to help her fall asleep.

thank u mam

babies that are under 2 months of age might have their day and nights confused . try to have routine shorter day naps and enough play time . allow your baby to fall asleep on his own in his bed rather than your lap as this will lead to a sleep habit hard to break later on . be consistent
