11 month old not sleeping through the night..

Hannah

My 11 month old is formula fed and I cant get him to sleep through the night. Starting at midnight he wakes up every two hours. I would try to let him cry it out but he crawled out of his crib early and we had to transition to a toddler bed so he wouldn’t hurt himself, so when he’s mad he gets out of head and beats on the door. We have tried rubbing his back but it takes literal hours to get him to fall asleep. Any suggestions?
