I do both.
Why I buy some toys...
I can't form Plexiglas, so I need to buy those (Emmi's favorite toy is plexiglas tabs on stainless steal chain) from the bird shop. That's just one example of stuff that would be hard for me to find the pieces to make. Or think of! So those types of toys are bought. Since I'm a preschool teacher and make sure I have lots of different materials for the children to explore, I want the same for Emmi. I'm crafty! But there are some things I just can't make.
Why I make some toys...
Since Emmi is still young and new to foraging. I started her off small and every few days to a week, I take it up a notch. This way I know where she is at developmentally (I'm sorry, I'm a teacher and I can't turn it off lol) and don't have to run to the store to buy a harder foraging toy every time she gets too smart. Emmi loves ripping paper. Most of the toys with paper that I have seen...unsafely made! I see this a lot. That or $15 for a toy that will be destroyed in two days? No thanks! (But thanks for the idea! I will make it at home, using safer materials and for much cheaper!) Sometimes I get an idea for a toy and just can't find what I'm looking for in a store or online. I order or buy the parts and make the toy. If she does not use it, I can tear it apart and put the pieces with other pieces she will play with. All of a sudden she likes the previously undesired pieces and yay! More enrichment! Plus, I know what she likes to do and can make toys that I know she will love. Who wouldn't want a personal toy maker? That's living the high life.
There are toys that just can't be bought or can't be made at home. Buying and making toys ensures Emmi is a very happy Green Cheek...And I bet making toys have saved me at least $100 so far.
