This is in no way a big deal to me - I'm just interested in other peoples opinions.
Went to see my SIL yesterday with my 9 month old DD, SIL has a 2.5 year old DS we'll call 'cousin' - cousin isn't very good at playing with other children despite going to nursery full time. Can't be trusted at softplays and isn't allowed to play freely because he will snatch things / push others.
Cousin has a specific toy he loves very much - he has many versions of this toy.
My DD is playing happily with other toys and then spots one of cousins beloved toys and starts stroking it. Immediately SIL snatches the toy away and gives it back to cousin (even though he wasn't playing with it in the first place) she then says 'toy' is sacred and can't be touched by others! So my DD is only allowed to gaze at the toy accross the room while Cousin hogs it.
I think its ridiculous! Its basically showing Cousin that he does not have to share his toys if he doesn't want to.
