DD1 (5, rising 6) has been a good sleeper for several years now for the past couple of months she's been really hard to settle. She stays awake till 9 or 9:30 and keeps appearing downstairs with extra requests/complaints etc. Last night it was nearly 10 before she actually settled down properly to sleep. I've tried putting her to bed earlier/later/letting her go out for a run about before bed/making her stay in and play quietly and it doesn't seem to make a difference. She's clearly tired and needs more sleep though, and I want my peaceful evenings back. Any tips? Am thinking we might need a wind down routine but I'm not sure what to add in. We already have bath (most nights) and stories.
