Most fen are baby-friendly, some of us fatuously so. A small but quite outspoken minority, however, are not. Be prepared to sneak out of any event where the darling child starts to make noise; and adjust to the fact that the aforementioned minority feels that those of us who bring babies to conventions are imposing on them and diminishing their joy with our noisy brats (all non-silent children are noisy brats, you see).
