Diaper help!

Ab

So ever since my son was born he’s had tons, and tons of diaper leaks during the night. Like, soaked through his clothing onto the bedding leaks. We’ve tried a plethora of diaper brands, ensured his penis is pointing down, moved up a size at night (he’s a size 3 during the day, 4 at night. His 3.5 year old sister is a size 4 at night and he’s out peeing her!) were just at a complete loss of what to do. I’d say he pees through his diaper at least 3 times a week. Oh and we’ve tried 2 brands of overnights and they also didn’t work for him. He just peed through them.

He does nurse at night randomly, and this isn’t something I’ll stop doing for him. But he’s also not nursing a full feed at all. At most maybe 3 or 4 minutes, likely just for comfort.

Have any of you had this issue? What did you do?!! I found these diaper liners on amazon, but not sure if they’d be truly helpful?
