I know! It doesn't make sense, especially as there are thicker nappies in the wash like the cotton ones. It's just a bit of a weird smell, can't explain - just not fresh like the others and I traced it to them. I'll maybe try another rinse with them. They need some more prewashes anyway. They are nearly dry now and it's still there. Maybe I'm just imagining it! Just don't want to use them smelly and hubby has more reasons to complain.
What do you line yours with and do you boost?
