Hi. I have a little three year old girl, who I obviously think is the greatest. She is a sweet kid, much like other little girls (and boys) that age. We live in central London and have recently started to encounter a real problem with a nasty little bully of a boy (probably about 6 or 7) who happens to be at a lot of the same playgrounds and jungle gyms that we attend. He will typically hit my daughter (jab fingers, punch, throw hard plastic balls in her face from close range at the jungle gym, call her "poo", hit me, etc). I have had words with her father (a shaven headed individual) who doesn't seem to see there is any problem with his bigger son repeatedly hit my smaller daughter. I am at a loss as to what to do. I get sick to my stomach when I see them, they always come up to us and taunt us and physically abuse us. I obviously can't push the kid away, words don't mean anything to him and his father is a yob. Any thoughts on what to do? All I know is his first name and the school he attends.
