I went to a normal MG and a young mum's group.

Huzzah for older mothers who teach their children about sharing so children twice the age of my child were told off for taking his toys. (And I do mean his toys, favourites from home so I could have a chat.)

Yes, it starts too early. But if you don't start it now, when do you start it? Inevitably too late. Which is why I told DS to "apologise" before he could talk or realise it's wrong to take toys.
