They have in our home. LO's temper has come out and she is being defiant. We have to repeat ourselves over and over again to get her to do certain things. And she has been very vocal about what she doesn't like: "I don't want to get out of bath!" "I don't want to go home!" "I don't want to nap" "I don't like it!" These are the phrases that seem to pass out of her mouth all the time now. Not to mention the screaming, crying, tantrums.
I think this is the terrible twos. Have they shown up in your home yet? How?
