OMG poor PJ and poor Mommy too - what a day! I am so sorry. I am glad RJ is ok and its just some bruising though. dont worry - he will heal and be A-Ok!
Glad to hear nothing is broken. I hope you both get lots of rest tonight and things look better in the morning.
Don't feel bad, DD had an accident two months ago and I literally ran around the couch, like a DOG, crying and holding her because I thought something awful...it happens to ALL of us.
