I KNOW they're only 3 (well, the other girl is almost 4) so therefore I know 'friendships' shift all the time at this stage and that when they say these things they don't have the same meaning as it would from an older child.
But...
I have always been rubbish at female friendship, was walked all over by friends at primary school and then badly bullied by girls aged 12-14. I want to start from the very beginning with my own DD making her resilient to all this sort of crap, making her know what a good friend is, and how to be a good friend herself.
Today she came home from pre-school upset because her 'best' friend nad her had had a falling out (standard stuff for them, I would actually say they're more like frenemies than friends and often fall out over sharing and things) which had ended with the friend pulling another little girl away from DD and saying neither of them was going to be friends with DD any more (fyi I am as certain as can be that this is what actually happened. In fact I have witnessed with my own eyes this particular girl saying this exact same thing to another child, plus I have actually heard her mum say her daughter said this about yet another child!! Mum is lovely btw)
Look, obviously it's no huge drama but I hadn't really expected DD to experience this sort of thing so young (all the other little girls at pre-school seem not at all the sort to do this, they have their quarrels about sharing and stuff but nothing yet along the 'you're not my friend any more' lines)
I told DD her friend shouldn't have said that and that if she says it again, DD should just go and find something else to do (which in fact today, I gather, she did; she went off and played with sand)
But is there any other advice for how to handle this if it happens again, in terms of what I tell DD? I had SUCH a miserable time with mean girls growing up (not saying this other little girl is a mean girl, btw, I know she's only 4!!) that from the very start I want to try as best I can to set DD up to be resiliient and know how to deal with this kind of thing?
I know it seems a tiny thing but it sets off such alarm bells for me and I was never ever given any help/advice by my own mum which I know contributed to my own problem.
