I take ds out and about a lot - both to "normal" toddler groups and to various activities for children with special needs.
And I feel that ds and I don't really "belong" in either. At the "normal" groups he stands out because he is so extremely shy and because he can do a bit less than other children his age, and because he's small. But at the special needs groups he stands out because he has far less problems than the other children there, so I feel a bit of a fraud to take up the time/resources/staff that another child might be more deserving off?
