how long can a baby (B4 18 weeks) wait B/4 having to be let out to potty? Do you take them with you before they're totally potty trained, or can they stay home a couple hours. Do they catch on after a couple months or how long does it take?? After they're trained, they're leave-able at home..right? I mean, of course not for hours on end, but like for a little while. (like....3-4 hours) Some people say they're trustable 6 hours...????
