Why is my 2 year old sleeping at 11pm?!

Question

For the past few nights my 2 year old has been falling asleep after 11pm, sometimes even 11:30pm. He’s not unwell, his routine hasn’t changed, everything has been normal. 
I wake him up at 8am as normal, his nap is at about 12:30pm for one and half hours MAX, so usually by 2pm I wake him up myself as he can definitely sleep longer. 
Nothing has changed, I keep him busy for the rest of the night, however still he’s sleeping so late. I watch for overtired sleep signals and there aren’t any! Does anyone have any tips on what I should do? Will this be a long term thing? It’s driving me mad!

Answer

What time are you putting him in bed and what is he doing between that time and when he falls asleep?

Answer

Are you saying he's not falling asleep for bedtime until 11:00 p.m.? Or do you mean he is sleeping late in the morning until 11:00 a.m.?

Answer

Maybe it's time to drop the nap and put him to bed earlier. Toddler need about 10-11 hrs of sleep and it sounds like hrs getting close to that but if you want him to go to bed earlier then drop the nap

Answer

Probably a growth spurt
