Overnight diapers

So my 12 week old has thankfully started sleeping through the night. I tried to find him some overnight diapers, but I can’t find any brand who makes smaller than a size 3, which is for 16-28 pounds they say.

He is only 13 pounds so I’m thinking they would be way too big for him. He currently wears a size 1 diaper but could probably move up to a 2 soon.

Any idea if the size 3 overnights might work or know a brand who makes overnight smaller sizes?
