Conflicting parenting styles with friends and their daughter

We have become good friends with a couple who have a daughter just slightly younger than ours. We were all friends before kids and we love them, they briefly moved away and had their kiddo, and after moving back 2 years ago we’ve started to have more play dates with them. We all thought it was wonderful that the girls are close in age and that is grownups get along. The problem is, the more time we spend with all of us, the more our daughter dislikes playing with their kid. Both girls are 5-6, and our daughter is very gentle, passive, she loves to share and play with other kids and is generally very agreeable. Their daughter is a lot more aggressive, she snatches toys away, she destroys Lego stuff on purpose, and shouts “no! Mine!!” which makes our daughter cry. Us parents usually try to offer a solution by guiding them - can you take turns, what about this, etc. However, their parenting style is to be entirely hands off. When their daughter yells, “no! Mine!” our daughter gets upset because it’s actually her toy. She tries to do what she knows and will say, “please don’t yell. Here, you take this one, that one is my favorite.. what about if we take turns?” But when it doesn’t work she looks to us for help or asks her parents. They say, “you girls need to figure it out, ok?” Which just leads to our daughter acquiescing and being unhappy. We can’t force our daughter to be more assertive but even if she was, it would just escalate. So what do we do? We really like these people as friends but they’re kind of sucky at discipline. Our daughter has started saying that she doesn’t really want to play with their daughter. And when we step in, it always feels weird because we don’t want to essentially parent their daughter. But there is only so many times we can tell our daughter what to do. Help! via /r/Parenting http://ift.tt/2hQhr5x
