bed sharing and transitioning to the crib.

hello ladies! i havent posted here yet because even though im an EBF, baby wearing, bed sharing mama, i didnt know if i was qualified to call my parenting style "attachment parenting"- but if anyone knows about bed sharing drama, it'd probably be you ladies! so here i am asking for a little bit of help/advice.

so, my daughter is 4.5 months old, and sleeping through the night, bed sharing. she naps regularly throughout the day without a fuss, usually in her swing or, will fall asleep in my arms, sometimes while running errands in the car. shes a good little sleeper. BUT recently, daddy has been sleeping on the couch because whenever he sleeps in bed, hes such a restless sleeper that it keeps her up, which keeps me up. bed sharing is clearly not working for us as a family so, i've decided we need to make the transition. my heart hurts over this but, i know its best for our family. with that being said, anyone who has made the transition, can you give me any tips/advice- on either what worked for you or, how to stay strong (as lame as that sounds) while doing it? any good books you read that gave insight? i know every baby is different and things arent universal when dealing with babies and sleep issues but. ya know, any advice or encouragement would be helpful!

*note: im not planning on trying the CIO method, i feel like that would be a betrayl of the trust between myself and my daughter. 

other than that. . . advice?
