Hands Are Not For Hitting

Noa had a rough day at Rita's house... she hit 3 friends.  I'm not making excuses for her behavior but she was hit too, just not sure who hit first?!  She also had an accident during nap time.  Potty training is still work in progress... the last 3 nights she wet the bed and she doesn't always poop in the toilet. We have been potty training for a month now.
