This is the Gingerbread house my little one did. I used 2 graham crackers 1/2 for the bottom. 1/4 for each side and another 1/2 for the top. I used very little icing. Cupcakes and cookies have more icing than this so I don't think it is all "that bad" for my little one.
This is the tray of things I gave her to decorate it.
Pictures of her decorating it.
This is her finished house. Not bad for a 17 month old!
