My son says some of the cutest things sometimes! Here are a few that I've remembered to write down lately:
When we're having lemonade he calls it "leNoMade". When we try to correct him he says it wrong but with emphasis - as if that fixes it.
When he doesn't know how to do something instead of saying "I don't know how" he says "I can't how", only he is usually whining and drags out the how so its "I can't hooowww".
He's also gotten into the "why" and "what is dat" phase which is more annoying than it is cute.
