Tandem mobi infusion patch cover

Hi all, I have looked online and just am not sure what to purchase. Any recommendations for infusion site patch covers. It isn’t lifting but it’s on my 9 month olds upper buttocks and close to the diaper area. I worry if he has a blow out or something, or if we move to the front and he pees out the diaper. Just something to give the a little extra protection. We don’t have a lot of site options unfortunately since he is so small. Thanks!
