Hi NC. That is the problem isn't it? It is usually us who are tired and grumpy and make things worse by overeacting/not reacting in a constructive way.
Have book right here and am going to go through it bit by bit!
First part is to Acknowledge Negative Feelings instead of ignoring them:
instead of:
DC "you're always with the baby"
YOU "no I'm not, haven't I just read to you?"
try:
YOU "you don't like me spending so much time with her"
instead of:
DC "he said this"
YOU "oh, just ignore him"
try:
YOU "I bet that made you angry"
instead of:
DC "he does it on purpose"
YOU "so what"
try
YOU "you feel he does it to annoy you"
etc
I have exactly this problem, DS (1) keeps trying to take DD's (3) comforter. I just say "no he isn't" or "just let him have it, no big deal, you'll get it back". She then goes and snatches it.
I now intend to try the "is that making you feel cross?" and see what happens..
