@Leialou's question got me thinking - We have a great library close by and we've gone to story time there, but LO is only 4 months and my husband thinks it would be gross to check out age-appropriate books since he'll probably just stick them in his mouth. That makes sense to me (though I'm less of a germaphobe).

When did you (or do you plan to) start letting LO check out books from the library? Were you concerned about kiddo slobber if you did it early on?
