I usually do play, dinner, bath, story time, then start keeping it quite in our room

Try not to play before bed.

Try dinner. Play, bath, story, quiet room. If he plays right before bed he's now overstimulated and that's the gear he's in.

Typical night routine; dinner around 5pm, than bath, play before bed , bedtime is usually around 7 PM @latinspice

What kind of routine do you have for him?
