Hi Dr. my baby boy 18th months he is sleeping time at 11 to 12 night time past 1month like this . Actually he is sleeping at 8 to 9 night time. Why he is not sleeping why timing changes…how to normal time sleep.plz tell me quickly

A. A lot of times parents increase the data and nap or give more nap is in the day more than one then that time they don’t get tired and sleep late so avoid giving daytime nap totally for a day or two and then you will see your child will learn to sleep early automatically
