Helping Those Who Don't Fit In

Earlier this year, I wrote about helping children include others in their play. It all seemed so easy then. Teachers just make it clear that children can't tell others they can't play. I know it is the right way, but when the child who wants to play is annoying and disrupts the play, it sometimes doesn't seem fair to the other children who are engaging in sustained, imaginative play.
As I write this, I am trying to think of solutions for the teacher who brought me this problem. I know we have to teach the "outsider" better skills, but that won't happen over night. Meanwhile, unless the teacher is right there to guide the play, those children who might move onto more advanced play miss out on the opportunity. Staff can try to involve the child in play with others, but again they are spending the majority of their time working on the skills of this one child, while possibly not giving the support to others who need it. The alternative is not a consideration. Teachers can't condone the children excluding, nor can teachers insist the children include and not be there for support. Playing with one child is sometimes easier than playing in a group, so maybe helping this child develop a friendship with one other child would help. Not a perfect solution, but maybe one to try for at least part of center time. If the teacher looks for this child's strengths and has him/her use them, to help other children, it could increase the possibility that others will see him/her in a more positive way. The adults need to make sure the other children see, that adults like this child and thus build the child's social value.
Thank you for being my sounding board on this problem. If you have insight to share, just post it in the comment section.
