As the title says, our 3 year old is waking and coming up to us multiple times every night. She doesn't appear to be upset or scared. She often has some pretext, usually her duvet has come off, but just as frequently she 'wants to ask a question' (which she randomly thinks of, such as why do we have walls), or she wants us to pick a teddy up... She generally just needs tucking in and a kiss and then goes back to sleep by herself. But it's still waking me three times from deep sleep for no apparent reason. We also have an 18 month old who has only just started sleeping through.
I should maybe add that our 3yo was a terrible sleeper till 13 months, but since then has slept well till a couple of months ago.
Any ideas about if there's anything we could do would really be appreciated.
