At this age my DS1 needed a pretty decent wind down, but we had to change it up to suit his needs. For example, before we he would have his bath and then we would do wind down in his room - put on pyjamas, brush teeth, read books, then bed. When we started noticing he was resisting bedtime, we changed it up. After his bath he could come downstairs, watch a short show and have a bedtime snack, then pyjamas, brush teeth, books and up to bed. This seemed to suit him better as he needed more time to wind down, but not just in his room, kwim?
