This is a really minor thing but it's been bugging me for months. DD (4) always kisses me and her DF on the lips, and her friends too (though she's less kissy with them now than she used to be). I don't mind, it doesn't seem odd to me, but obviously I'm thinking out there in the real world we don't all kiss each other on the lips. I sort of want her to know that, but I think she'd be devastated if she thought I was criticising her affectionate behaviour, esp after all this time... What do you think, just wait til she works it out for herself?
