Can you make BBH fold ups soft again?

As the title suggests, can you make the fold ups and boosters soft again? Any tips very much appreciated!!

Do you have a dryer? Belt them in that for a bit, or scrunch them up with your hands for a while if you don't

Yep, I second the dryer. Although if you have the hemp ones, they're a little tougher to soften.

This is a technique I've read for refreshing and softening towels, but it might work the same for nappies. Wash them twice. The first time wash them wish vinegar in the water, and the second time wash them with bicarb in the water. I'm sure you could probably google the ratios you need

Hang them out in the rain. Then rub them on the carpet for five minutes.
