I have a 10 week old who will only nap if I'm holding her and WALKING around. My neck and back are killing me from holding her all the time. She hates a baby carrier and I've tried the Bjorn and Moby wrap. She knows instantly when I sit down even in my rocker. It's funny how she knows the difference between walking and rocking! What can I do to help her nap on her own or am I out of luck until she gets older? I can put her in her crib and swing and she just stays awake for 30 minutes to an hour lying there until she fusses and cries to be picked up (at this point I'm sure she's overtired) what can I do???
