My oldest is almost 4 and he got lots of fun toys for Christmas that he wants to play with. Things like Legos, little playsets, games etc. I want him to be able to play with them, too! But I also have a mobile one-year-old who is in everything, and is driving my son crazy grabbing all of his toys. We have basically said that he can only play with those things while the little one is napping or sleeping. But I feel bad because it's such a short amount of time that the little one is asleep when the oldest is awake. Does anyone have another suggestion?
