My 18 month old started regularly soaking through overnight diapers several months ago. He is already in the size 6, so I’ve tried adding a sposie diaper liner. It worked ok for a while but lately he’s been soaked through more mornings than not and I’m constantly washing crib sheet and sleep sacks.

We were using up&up (target) overnights, and when those ran out recently I bought huggies to see if that might help, but I think it’s actually worse.

What’s the next step? Is there a next step?
