Oh my. Anyone who thought charcoal boosters were the answer for their heavy wetter will love these hemp super-boosters.

We can never quite believe that something this slim can be quite so thirsty, making the hemp nappy booster an ideal choice for heavy wetters and night-time use.

They're so absorbent that when one of our product testers tried these overnight, she panicked that her baby was dehydrated (don't worry he wasn't) because the insert was so dry!

And because they're made from hemp, bamboo and cotton, we're loving their eco-credentials too.

As quick to dry as bamboo (although slower than charcoal) these are also convenient if you're washing a mix of bamboo and hemp.
