I have a really good group of friends that I met when my DD was born 2 years ago and I still see them on a weekly basis.
There is one child who is really badly behaved and keeps hitting all of our children. His mum just sits and chats rather than follows him around and if she sees him being spiteful she shouts across the room which scares everyone in the vicinity! However he is still horrible regardless of being told off and we have started to go on days out/have playdates without her. I feel really mean but I don't know what we can do about the situation tactfully? Any ideas?
