I have a friend with two year old twins that came up with these really neat alphabet cards that are made out of BPA free food grade plastic, sized the same size as credit cards. I would love some for my little guy, who always takes my credit cards out of my wallet. She is trying to raise funds to start the project on Kickstarter. For not a lot of money you can be one of the first ones to have a set. I am not going to benefit from this in any way, other than getting a neat new toy for my very busy toddler. Check them out!
