I am keeping my aggressive 4yr old at home mostly. The only place I take him out is places like temple so that there very few children present for him to hit unprovoked. If I take him to malls and on seeing a kid his age or younger he hits but some Singaporeans in mall make it worse by shouting directly at him....inciting him more. I wish they would just pass by and let me calm him or control him. I know nobody likes their child to get hit but if only they try to understand. May be it's asking for a lot.
