seeking advice: tummy sleeper peeing through pjs at night

Leah
Hi all! I am hoping you might have some advice. My 6 month old little boy has now started sleeping on his tummy at night and this has resulted in peeing through his pjs every night and waking more frequently. I have tried double diapering and putting an overnight maxi pad in the diaper. Neither solution worked. Anyone faced this and found a good solution?
