co-sleeping crib transition??

Addie

hey Mama's!

I'm bed sharing with my 15 week old son, but I want to start sleep training next month when he turns 4 months. did you co-sleep and then transition to crib? what did you start and how long did it take for the transition to take? I love bed sharing, but he wont take a nap longer than 30 minutes and I'm wondering if bed sharing is to blame. as much as I would like to nap as much as my baby I got things to do! haha
