I just bought the pea pod due to all the great reviews on amazon. We introduced it last week just to see how it would go over. So far my son (18 mo) has had fun playing in it, but it does NOT seem like he will sleep in it. In fact, he was fine when he could crawl in and out on his own, but he freaked out when we tried to zip it shut with him inside. For the price I don't want to keep it if it is just going to be a "play tent", but for the convenience I would love to use it for travel. Any tips on actually getting your kid to sleep in it?
