I think it depends how you set it up. If she is YOUR friend and you say lets get together and you bring the children along then thats fine. I would not set it up as a play date for the kids. I have friends who I meet who have kids different ages and the kids sometimes play but usually do their own thing. Playdates I set for my kids are only with their friends or people they want to play with. Hopetthat makes sense.
