Good morning i have a 9 months old boy he doesn't sleep he's always hyper active during the day he plays and at night he also want to play we tried switching off the light thinking he will be scared but he plays in that situation. is it healthy?

Avoid night activity: Babies more than 3 months old can usually be trained to sleep through the night. Younger babies might go 6 hours before feeding, but the older babies should be fine until breakfast time the next morning. Do the same relaxing bedtime routine each evening. Generally, a parent puts his baby or toddler to bed, says goodnight, walks away, and stays FAR AWAY until morning. Works for 3 year-olds too.
