Hi Your concern is your 3.5 year old son showing aggressive behaviour. It is necessary to determine the reason behind his behaviour. It could be because he wants space to run around and play or it could be because he is not getting enough attention. It is good if your wife’s mother wants to come and help. Consult a psychologist and explain about your sons behaviour. A psychologist would like to know about the kind of food he eats and his sleeping pattern. Create a warm atmosphere for your son. Try to not worry too much.

Hi... Please consult a Child Psychologist or a Pediatrician. This kind of aggressive behaviour is common among young kids when they feel neglected or left out in terms of love and attention they desire from their parents or significant others. They may develop a competitive feelings towards their younger/older siblings if they are getting more attention. You need to try to replace this feeling of competitiveness with being protective and caring towards towards their siblings. Try making him an elder figure who is responsible to take care of his younger sister. You can try giving him some responsibilities and appreciating him for his small efforts. You both need to make sure that he doesn't feel left out while you both are busy taking care of your young daughter.
