My DS2 is wildly smitten with one of DS1's friends. DS2 is 2, the girl he's mad for is 5.
It's quite funny, really, but also a little weird. He talks about her all the time, and can point out her flat from four or five different routes. He is thrilled to see her, whenever ... and then has nothing to do with her. He never plays with her (she has a brother closer to his age). He sometimes gives her hugs, and that's it.
Anyone else have weird smitten children?
