Things I do with my two year old:
Maybe Jiffy Pop popcorn
Bake (muffins, cupcakes, brownies…anything he can help with) beware, it can be quite messy!
Walks around the neighborhood
Going to all the parks in the neighborhood
We have memberships to the local zoo and children’s museum. It saves so much money, and we can go for an hour or two every other week. You definitely get your moneys worth from memberships.
Indoor playgrounds, usually free for adults. Indoor bounce houses, or gyms is what you should google. Some malls have them as well.
Not sure where you live, but we have a couple orchards near us and I go to the main one in the area, lots of yummy foods, and it’s free to feed all the ducks and chickens and goats. They also have a large playground, hay rides and mazes.
