Youngest DC is 5. Always on the go, literally nothing wears them out. You know at parties where the kids are running around solidly for 5 hours and all the adults laugh and say oh they'll sleep well tonight and their kids all fall asleep at 6.30pm? Our DC will still be awake at 10.
We've always had a solid bedtime routine and good sleep hygiene - bath, wind down, books and bed. Eldest takes ages to fall asleep and used to need us in bed with them, but since age 6 has gone to sleep (albeit slowly) by themself. Youngest however WILL NOT stay in bed, let alone go to sleep.
Had a dummy until quite late and we realised when we took it away that it was the only thing helping them sleep. Spent a few months tearing our hair out, then tried melatonin which was amazing and we enjoyed some heavenly evenings of managing to get DC to sleep by 8.30. However, I don't feel comfortable giving the melatonin (gummies/droppers) as I know the things bought from the US are unregulated and there aren't any long term studies on side effects. So... we stopped using them again, only to return immediately to the land of no sleep before 10/11.
So... wise people of Mumsnet, is this just regular 5yo behaviour and we just need to resign ourselves to another couple of years until they're old enough to have hopefully calmed down and stay in bed by themselves, or does this sound OTT even for a lively and active 5yo?
School haven't said anything about hyperactivity or inattentive behaviour, so unsure whether ADHD is likely (although DP has it so we're aware it's a possibility). Eldest sibling is autistic.
For wider context, they don't stop moving EVER. Always climbing, jumping, dancing, doing cartwheels, talking endlessly, very rarely listening. Absolutely lovely and delightful, creative and caring little soul who is wonderful in every way - just very, very tiring!!!
