Crib transition help!

Paloma • 23, wife and mother 12/21/16 💙

So our original plan was to start transitioning our son into his crib at 6 months, and now here we are at almost 9 months, still co sleeping with him. I've tried putting him down for naps and the most he'll sleep is 30 min then wakes up screaming! And half the time when I go to set him in his crib, it's like he senses it and wakes up right away. Any tips to a smoother transition, or please share your experiences on moving your baby to their own room!?
