This too shall pass...RIGHT?

I'm sure it's a phase. I hope it's a phase. Lately, Caden wants what he doesn't want and doesn't want what he wants. It's driving me beserk. For example, we are going to the car and I say "Caden, do you want to walk or do you want me to carry you?" I'm into love and logic parenting with choices. So, he says "carry me," but when I go to pick him up, he has a total meltdown and says "I want to walk." But then he doesn't walk, he just stands there and cries because he wanted me to carry him. It's so tiring and the crying is taking on a Jaelyn-whining tone that is not at all good for my sanity. What to do??? It's a phase...it too shall pass, right?
