Maybe like everything else. Balance. toys, board games, our kids get highlight magazine for the puzzles (and they love getting them in the mail and waiting for them), online games. Even the plastic trucks from the big box store we have balanced off making some wooden toys ourself. Also buy the put together kits of little machines to put together with them. 12 volt cars (i had pics of one of them on here i think they have four of them now its a regular parking lot) All kinds of books. Balls to play with. Kids are a lot of upkeep!! Tv can be good too, but another one of those things that requires balance. shoot, give a kid a waterhose and some buckets they can play in the mud for half the day (just watch the water usage). we also use the hose and play "wash off outside toys" once in a while and go through cleaning the outside toy stuff. Rope swing. Gone through numerous swing sets. Trips to park, beach anywhere. All about balance.
Not every parent has this kind of time either, life is hectic, which is understood. kids are a LOT of work.
