Every morning, after Jude goes down for a nap, Jack does what Babywise calls "roomtime" - up to one hour of time in his playroom alone. Supposedly independent playtime in one place teaches kids to problem solve and play on their own, without mom's influence. When he was younger we did "pack 'n play" time, where he would spend time in his playpen with a few toys and books. But now that he's bigger and we have a fun playroom, he really enjoys his "roomtime" (it might help that I usually include a snack). And it works out good for me too since it's one hour in the morning (as long as Jude stays asleep) that I can work on my "other job" and make uninterrupted phone calls.
