Overnight diaper recommendations??

So my son is 3 1/2 months old and he's a pretty dang good sleeper at night. He'll usually go to bed around 10-11 and wake up around 8-9 in the morning. My problem is is that he already figured out how to flip from his back to his stomach and he'll flip over anytime I put him in his crib. I've given up flipping him over cause he'll just flip right over again. Right now I'm using size 2 Luvs diapers and he wakes up with the front of his body soaked. I'm looking for another brand that will actually keep him dry since he does sleep long periods. Any help would be appreciated! Picture of my handsome son for attention. 😍
