she doesn't sleep the whole night she sleeps early in the morning at 5:30 and wakes up at 8:00 o'clock after that she didn't sleep a whole day What should I do

A. hello just make sure the child is tummy full and also try to set a bedtime routine for the child and slowly the child will get used to it and will be all fine and even in the daytime try to follow a same schedule which would be a better option
