My toddler is 19 months old and he has very less sleep in the nights. He sleeps for 3hrs in a stretch and stays awake for 3hrs and then sleeps for 3hrs, that's it. How do I make him sleep continuously? I feel very sad for him as he feels sleepy but is not able to sleep. This is happening since past 7 months. I'm afraid whether he will be able to sleep continuously or not. Please suggest and help me
