Baby rolling on stomach at night, diaper leaking 😕

His doctor said that it is safe if he rolls onto his stomach on his own, but his urine pools in the front of his diaper and it leaks every single night! We use diapers one size up at night and this worked great until he started rolling to his belly. I have tried sneaking in his room and rolling him to his back in the middle of the night, but by the time I get back to my bed and look at the monitor, he is on his tummy again. I’m so tired of changing and washing bedding. last night, I woke him up and changed him and I felt so bad because he cried for 5 min before falling back to sleep. I know I shouldn’t wake him, but my work week starts tonight and I knew I wouldn’t have time to wash more bedding. Has anyone else had this problem? How have you dealt with it?
