I have a 2 year old son, who can be very happy and very sweet. He has recently began to do the following things.
never does anything we ask or tell him to do, he will just look at you and say no.
pull hair, hit, and pinch others.
gets so mad that he would ball up his fist and tense up to where you can see the vains in his neck.
He doesn't want to eat alot, however he drinks alot of fluids.
wakes up during the night screaming
He is extremly hard to potty train
We don't know what to do. Is this a normal two year old?
