Hi, My son is almost 2 (23 months old). He has suddenly become very cranky and starts crying for small things also. He has become stubborn and cries if we dont do what he wants. He keeps crying for 15 20 mins will start kicking in anger. and he has started doing this for even small things. from brushing to taking bath. is this normal foe kids of this age to do will this pass by time or should we do something about this.
