Hi, my 3 month old will not sleep at night and has developed a habit of crying before sleeping. Also he will not sleep in my lap, cradle or cot, he wants me to carry him on shoulder and after moving around for an hour he'll sleep. But his sleep will not be guaranteed. He might sleep for just 10 minutes. Rest he has no problem with his growth. Please suggest me, how do I change his habit and make him sleep at night.
