Why my baby wakes up at 7 am but sleeps at 9:30 or 10 pm

A. So your child doesn’t sleep at all in the day your child is super duper active but if the child is sleeping at a stretch through the night and wake up fresh in the morning then it is not a problem because a lot of kids have their own cycle and they sleep like this and what is most important the child should sleep for a minimum of 8 to 10 hours with your child is already doing so if you look at it there is no problem actually
