Not ready

I just walked in on Bear standing up at the toilet going potty. Not a big deal right? Wrong. He wasn't using a stool. I had to do a double take. He told me he was too big to be using a stool. Now granted he was raising himself up on his toes to reach but that just threw me face first into the fact that he is not a baby anymore. Or even a toddler. He is a boy. A big boy. I am going to go cry a little now...
