Transitioning from cosleeping to crib PLZ HELP 😯

Me

My son is EBF and cosleeping. He only falls asleep if I nurse or rock him to sleep. We also don’t have a great routine. He just turned 6mos on the 17th. Big sister will be 2 in two weeks and she’s on a great schedule, but I know he isn’t 😔 any advice? He has never taken a pacifier or bottle, two things that I always used for big sister at this age to sleep in her own bed. Please share any advice specifically for EBF. Thank you mamas ❤️❤️
