I have noticed my soon to be three year son's behavior change over the last few weeks. I am not sure if this is a testosterone surge of sorts but am not sure how to handle it.
He generally is extremely well behaved when at his child minder or nursery but at home can be very stubborn and a little mischievous. When he does not get his way he fights and torments his older brother aged 6 and often bosses him about. The older brother is very gentle and gets upset by this.
Most recently however he seems to be lashing out at us all with his nunu (comfort blanket) when he gets told off or does something naughty. The naughty stair does not work with him and if I take his nunu away he screams and cries tremendously.
Over the weekend we went to the beach and he through a rock at his cousin which split his lip. Then when we got home I called him in from outside and he through a stone through the window. Today I picked him up from nursery and was told that he was smacking other children. He is very sorry when we scold him and gets upset.
I know he can be feisty at times but we figured this is just him gaining his independence. The nursery and his childminder are forever telling me what an obedient and sweet child he is and they love having him around. I am perplexed by this behavior as we did not experience this with his older brother.
Any tips on how to deal with this behavior and nip it in the bud? Thanks in advance.
