No kids here (yet) but I'm planning on talking to them about what greek life is all about and how being in a sorority has benefited me. If they then decide it's not for them, I'll be disappointed but I'll respect their decision. Same goes for my hypothetical future daughter if she joins a sorority other than AEPhi - if she's happy in another GLO, I'll be happy for her.
Oh, I like the lullaby idea. We have a couple of pref songs that would make great lullabies
