Peeing through Diaper at night

My baby is 10 months and has been going L night without a diaper change.

Tonight I was rocking him back to sleep and noticed a warm feeling. Turns out he peed through his diaper and pajamas into me.

I need suggestions for best absorbent diapers

Do I size up? Get overnights? Size up over nights?

He’s in 4s and they fit perfectly right now.
