I have a friend with a 7 year old who never has any play dates, doesn't know any local children and rarely goes to parties. She goes to an after school club once a week but other than that, sees no children out of school (apart from her cousins who are older and that's only a few times a year). I feel really sorry for the girl especially as she is an only child. Her parents have really active social lives, seeing their friends several times a week (while the other parent looks after the girl), but they don't want to put the effort into facilitating the child's social life.
I have tried organising play dates with her and my daughter and the parents sometimes let her come here, but on the condition that I drive to their house, collect the child, do everything with the kids and then return the child. They are not grateful if I do it and I almost feel like it's a burden for them. I feel really bad for the girl, who in my eyes must be so bored. But maybe it's just because my children are so often seeing friends that my idea of what is normal is skewed.
Part of me thinks that I should offer to take the girl out more but I may end up feeling resentful as it's me putting in effort for the child when the parents aren't interested. The other part of me thinks it's none of my business and it's perfectly fine for children to not socialise much outside of school.
