My 7 daughter just turned 7 months and still sleeps all night in her swing. She wakes up after 45 minutes if we lay her down in her crib. It isnt even the movement of the swing that she likes (we dont even turn it on). I think she just likes the position of it. How do I get her to sleep in her crib? She is going to be too big for her swing pretty soon...and I just feel like a bad mom letting her be in the swing all night, every night. She sleeps like atleast 7 hours straight in it! Is it bad for her back? Any ideas on how to transition her to her crib?
