Toddler Loves Sleeping In The Bed😩!

My son is now 15 months old and LOVES sleeping in the bed especially RIGHT next to me. He does good some nights in the crib but he ALWAYS has to fall asleep in bed with me and his dad first and when we try and move him sometimes he wakes up then he’s up for the night... When we do finally get him to the crib I don’t know what it is but he wakes up at ODD hours SCREAMING!!!! He will still be asleep as he’s doing that. He doesn’t do that in the bed with us so I don’t know what’s going on. Any helpful tips for getting him to sleep and stay asleep in his crib. I have a newborn now that’s exclusively breast fed so he constantly needs to be on me too and it’s getting harder with a 15 month old me a newborn and my boyfriend all in one bed😩😩😩😩
