We (my 3 1/2 year old daughter & I) were actually having arguments over whether her last pair of shoes were on the correct feet or not ~
Me: Honey your need to switch your shoes, they are on the wrong feet.
E: No they're not.
Me: um, yes they are...
E: No this is the right way...
Not fun. I just bought her a new pair of summer shoes and thought to try this. Four letter names are just right but you could use initials if your kid has a long name.
So far so good. I'll keep you informed about the next disagreement, I've a feeling this is just the beginning!
