well i have g/b twins that are a little over three and let me tell ya boys are somuch harder than girls. Jonathan had it down for a couple of weeks then he started potting his pants again so we are back in to pull ups he will pee in the potty but #2 he has a problem with most of the time. What I do is I cut them both off about 1 1/2 hrs before bed time they are not aloud to have anything to drink except for maybe a few sips and then at bed time they get a sip. Allenna does very well she does not mess the bed. Jonathan wears a pull up but most of the time he is dry. as for not letting him get out we shut their door so they cant get out of their room (i know sounds harsh but we have a baby monitor in their room still and I am a light sleeper so if anything happens or if they have to go potty i can here them and let them go). I hope this gives you some help.
