DS, who is 3 & a half, has taken to saying this a lot recently. He runs faster, jumps further, cuts better etc than one particular friend (he says). Sometimes he says he can't do something as well as this friend. He sees quite a bit of this particular child, who is a bit older. I am good pre-kids friends with his mum, but have only recently been living in the same area, so they haven't seen each other much before the last 6 months (just to explain why this is a new thing). When we meet up we tend to chat & the kids go off together, I do sometimes hear the other DC saying things about how he's the best at colouring or he got a sticker for being the best at nursery etc.
Anyway - my question really is how to respond when DS says this to me. I try to say that everyone is good at lots of different things, & maybe he can run faster than friend but... then that feels like putting him down? & when he says that friend is better than him & he can't do, I find it hard to respond without saying something mean about friend! I don't think the friend is at fault or anything, but DS only talks about this sort of thing in connection with this friend.
This one is really pushing my low-childhood-self-esteem button I think. I'd appreciate some thoughts.
