5 yo's friend won't give her space, let them work it out or talk to parents?

My little girl is friends with a boy in her class. They both really like one another and were fast friends. Both have several other friends but took to one another. My daughter loved his stuffed animal and one day after school I found that his parents bought one to give my daughter. It looked like a birthday gift and I embarasingly contacted them to let them know she must have fibbed, it was not her birthday. They said they knew and that their boy just wanted to give her a gift. I thanked them and we arranged a yet to happen playdate. This was a few weeks ago.Another mom I am friends with told me tgis boy was holding my daughter back from giving her son a hug, he didn't want her to but my kid pushed him away and gave her buddy a hug goodbye. I was a bit concerned. I asked my daughter is he does not give her enough space, she said he was fine. The kid is very sweet and I know she likes him. Then today she tells me that he actually won't give her space and when she asks he he gets sad and she feels bad. Well I talked with her about personal space and that she should demand it and let him know if he can't give her space she will not be friends. And we talked about not allowing someone else's sadness dictate what she does in her life.So, she seems prepped. Do I talk to the mom as well or let them work it out? I'm torn. via /r/Parenting https://ift.tt/2HFqxBf
