DD is 5 months. She's a rock star night time sleeper, but we are NOT good nappers. Lately I have been finding that she will only nap in the stroller... not a habit I want to get in to! I try to put her in her crib when she is showing sleepy signs, but she NEVER falls asleep and letting her cry it out isn't really my thing (yet) Any suggestions? Or is she still to young to have a nap time routine?
