I have a 3 year old son who's behaviour has got worse over the last year! He constantly moving around talking climbing on thing, barking at people in the street and walking on all fours(sounds funny)! swearing constantly,Dose not listen to anything anyone says, hitting out, tantrums over nothing arguing, running on the roads when he has been holding my hand his sleep has began to change as well he used to go to bed at 7pm now he can still be up at 12 am full of energy even though he gets up at 6.30 am. since he was 18 months I did the naught spot and reward chart but now he just laughs when I put him in to time out! I don't shout and stay firm but really don't no what to do. Seen a doctor and he said this was typical 3 year old behaviour. Which I no this is not normal even family members have commented on my child. My sister is a child practitioner and even she said this is not normal for a 3 year old! I just don't no what to do now?
