I need advice on sleep training. My 1 year old was sleeping in her bed as soon as she came out. I refused to have 2 babies in my bed since at the time her sister was not sleeping in her bed all night and would come in my bed. Well we spent the day with family and friends for Thanksgiving last year and she got held a lot and since then it has been like pulling teeth trying to get her to sleep in her bed! Like literally 1 day undid everything I had done and she would only sleep in her swing. Fast forward she just made one and she still sleeps in the swing and will not sleep in her bed! With her sister I let her play in her bed a lot to get use to it and would let her fall asleep in there by herself until she now sleeps in her bed all night and she is 2. But my 1 year old is a completely different baby. She wants nothing to do with her bed and the let her cry it out method will not work since my girls share a room that would interfere with my 2 year old. She is currently laying in her bed with her bottle she just finished it so im waiting to see what she is gonna do. How can I get her to sleep In her bed.
