#asktheexperts my baby will be 4 month old after 3 days. For the past 10 days her sleeping schedule changed. she was sleeping for 6 hrs continuously at night suddenly it changed and she sleeps only for 1 hr and after feeding she sleeps and wakes after 1 hr and the process repeats. also some days her crying is out of control and after some time about 1/2 hr she settles. earlier I could understanding her cues but now I am confused and i dont know what to do.
