My 12mo has just started nursery. He’s always found it hard to switch off to go to sleep and he’s a very light sleeper. At home he sleeps in a very dark room (even had to tape the black out blind to the window!), with white noise. At nursery, they have a separate sleep room but there’s no door on it so it’s obviously still noisy and whilst the blinds are drawn, it’s basically broad daylight. They have a white noise machine but it’s not as loud as our one at home.
At home he can put himself to sleep and naps well now (after lots of hard work) but he’s not napping at all at nursery, as expected.
I hope that he’ll get used to it eventually but for anyone whose LO’s were similar, how long did it take for them?! He’s so unhappy, understandably.
