What brand of diapers are you using because that might be the cause I’ve had the same issue
What brand of Diapers? Depending on the brand some have better absorbing abilities! I agree with the person above as well. Usually diapers leak when they need to size up
Try and use a sized up vest too 😊
What night underwear are you using? Because… wait let me look up a good night undie

We size up and someone else had recommended these. They work great https://a.co/d/jaxt3aK
Size up and get overnight diapers!!
Pad inside the diaper then a second diaper one size up over that. We dealt with leaks for months 😭
Size up the diapers. The diapers are small if they leak like that
