I used to have a 2 year old toddler, he had lovely manners and was very laid back compliant type of child. I don't think he ever had a real tantrum and was generally adoreable and lovely.
Now he is 3.5 and I really do wonder what happened... he still is the above on and off throughout the day but inbetween being his usual self he is aggressive, angry & whiny. He is deliberatley defiant (refusing to say please etc), he hits (even though there is zero tolerance on hitting) and he even recently went through a biting phase (which thankfully was short due to lots of effort from me).
I guess I want to know two things... is this normal and how do I deal with the constant barrage of 'pushing his luck' type behavior??
