I don't know about kids being that bad. I've got a five month old niece and I always show off pictures of her to girls. They all say how adorable she is and they say I must be a proud uncle. I even point out the drool on her chin in one picture, absolutely priceless!! Girls just dig it when you like kids.
Once my niece is older I plan to take her out to go shopping and stuff. Then have all the girls go "AWW, what an adorable little girl." Then they'll ask if she is mine and I'll say I'm just babysitting and blah blah blah. So this kid is cool, because I don't have to take care of her all the time!
