If all else fails.

My children slept beautifully from the day they came home
from hospital. However, at about your daughter's age
my two girls (a year between their ages) suddenly got the
idea that they wanted to stay up late.

I tried what's known as 'sleep hygiene' which is establishing a few routine cues that are supposed to signal that sleep is imminent.

As good as that all seemed and is, for many youngsters, it didn't work and my girls were wanting to sleep later in the mornings.

So, I asked them if they wanted to stay up very late and they gave an enthusiastic affirmative.

I said that I would allow them to choose their own bedtime if they could stay up all night with me and watch movies.

They thought this was great.

I let them choose a heap of videos and we settled in for a night at the movies.

I knew that I would last ok because, like you, I often stay up late (though I don't have insomnia).

As they drifted off to sleep I'd gently shake them awake and say, "Watch this!! watch this! You're missing it!!"

I kept that up all night and into the morning, when they gratefully flopped into bed.

Since that time they won't stay up EVER - they are so glad to get to bed. They're now in their 20s and laugh about that night - but they STILL head off to bed at around 9.00 pm.

Sometimes, when all else fails, give the people what they want - and rather too much of what they think they want.

There are lots of good (gentle; creative) suggestions that have been made on the board already. By all means try them, but in the end, if they are not successful - behave in an unexpected way. This strategy might work for your little one.

It worked for mine

Good luck with it.
