haha try hide n seek, my boy 3yo, let him find u (he likes to do that), but must let him find u, dun make it too hard to find cause he will lost interest, play water bubbles, let him run around in the garden, play inside my car, when i need to vacuum and mop the floor, he wanted to help, so give him sweeper and mop n play along together

And ask them to do household chores.
