Just a note here, I can't remember if I've posted about this or not. I love snack sized containers! I like to get them from the grocery store, dollar store, or ichiban kan online.
My kids see a snack and they go crazy eating the whole thing. So, right when we get it home we put it in snack sized containers. We also do this with yogurt, homemade jello, and anything else that needs portion control.
