I believe children can be taught everything from a young age. So I want to foster in my 2 year old and 6 month old sons to wake up in the morning at 4:30am, when we can play and have breakfast. Next year he can use this time to study and learn his prayers or read a story. Is it worth trying? How long should he be sleeping for? Can he have breakfast that early in the morning? I believe it will make it easier for him when time comes for school :)
As a first step, it’s likely time to separate them and have them sleep in separate cribs. Not only will it likely help them sleep better at night, but there are safety concerns with two of them in a crib, especially as they start being able to climb. In addition, be sure to establish healthy sleep habits, including a set bedtime, a consistent bedtime routine, and having them fall asleep on their own.
