M is 10 weeks old and for the past two weeks she has NOT been napping. All she ever does is take 15 minute cat naps in your arms. The second you put her in the crib her eyes are wide open and she's ready to go. The funny thing is she's not cranky because of the lack of naps. She's usually cooing and aahing and smiling.

Any one else's LO not nap?
