Do you still read them stories? Do they need tucking in? Do they put themselves to bed? What time? Mine really struggles getting to sleep. Ours have baths. We still do stories, have a chat about the day, hot drink. Bedtime is anytime between 8 and 9 but not very independent -needs a lot of handholding. Younger sibling is fine with a 'night' called through the door. Just wondering what's usual at this age.
