My daughter is 7 weeks old. A couple weeks ago we finally have been able to get her in the crib for naps versus napping on us (yay!). However her naps are anywhere from 30 minutes to an hour but then she will continue to nap on us for an hour or more. If I try to put her back down she wakes up. Any thoughts/suggestions to help her take her whole nap in her crib? She sleeps for 5-6+ hours in her crib at night so I'm not sure what the problem is.
