One thing I do with my kiddos is get them outside for the 30 min before dinner and about 15 - 30 after. I found my boys just have a lot of energy and by allowing them time to burn it off they slept so much better at that age.
Yes, I know it is hot, but with water and shade, they are just fine:) Also depending on your house, ride on toy races (I'd time them) and simon says that consists of a lot of jumping and skipping help, too.
The key is though after getting them "all riled up" to be there with a book or game that is quiet to calm down, then bath, then book again, then bed (or whatever is your routine).
Best of luck!
