Tegan this is oh so normal, as everyone else as said. As Magic said the follow through is what counts in the end (of course after you pick which battles are worth it to start with).

My son has gone from this to now saying "huh??" everytime I ask him to do something and even if you repeat it he says "huh???" as though he doesn't understand but if I pull myself up and not jump in with the repeat it's amazing how many times he has actually heard me and is just delaying the envitable or hoping to distract me.
