I'm always on the look-out for easy homemade toy ideas- especially those that use items I would otherwise have thrown away. So when I found in a book recently a use for old yogurt containers specifically for 15 month old toddlers I was happy to try it.
I cut a hole in the lid of a container, and tied a piece of string to a clothes pin. The idea is to clip various objects to the clothes pin and allow the baby to "go fishing" by reeling in the string and pulling the objects up through the hole.
It is supposed to be a brain stimulating activity because the objects get stuck, and they are supposed to work with them until they come out. So far, though, my daughter hates the idea. It frustrates her to no end. Oh well, I'll try again in a couple weeks and see if she warms up to the activity!
