Weaning into crib

Autumn

I need help on trying to get my baby to sleep in his crib. My boyfriend (his dad) & I have co sleep since day 1, but he’s just so squirmy now he really needs to go into his own bed. We’re putting up his crib tomorrow. Any tips or advice to get him to sleep in there because I know he’s just not going to have it.. he’ll be 5 months old October 15th.
