ALL children have the capacity to be sweet loving little things BUT there are times when they are the exact opposite. With special needs children there is more likely to be extremes of behaviour. A 10 year old that runs up and grabs you and kisses you - inappropriate in most daycare situations and at other times that same child will try to hit you because they didn't like being asked to do a particular task. My special needs daughter (trisomy 12p) just turned 19 this month. I live it 24 hours a day and often have a child with special needs in my home. In a home sitiuation you can expect to see more of the extremes of behaviour than in school because the child will come to feel comfortable and like they are at home and will need reminding of your rules. Ask the parents exactly what they allow at home especially in the area of "personal space" and how they let him know that he is overstepping the boundaries without upsetting him.
