My 2-year-old boy has been sleeping late eg 10pm and wakes up as early as 7am. I'm concerned that he may not get sufficient sleep. Any suggestions to coax him sleep earlier?

What I do with my 17m is to tuck her in bed and off the night. I will stay with her for as long as she needs to get to sleep. I sing to her and pat her. Maybe you can try doing this method?
