Thirsties Care Guide

  • Wash all nappies once before use. Prewash any hemp products separately for at least 3 times. The hemp will reach full absorency after approximately 8 washes.
  • Wash dark colours separately
  • Wash with non-bio powder
  • No harsh stain removers or bleach. They may cause irritation and can damage the waterproof membrane
  • Don't use pastes of nappy powder directly applied to nappies as this is too concentrated.
  • No fabric softeners. They will reduce absorbency.
  • Rinse nappies prior to main wash. Or Prewash (small amount of detergent optional) but this will subject the nappies to more 'wear and tear'
  • Main wash with max wash temperature 60 degrees.
  • Line dry. Can be tumble dried on low, but ideally no more than once a month to prevent premature deterioration to the nappy.
  • If using a nappy cream always use a nappy liner - ideally a disposable paper liner.

Not BTP for us unfortunately

I really love this fitted nappy, its slim, soft and very absorbent. Unfortunately, we have stopped being able to do it up at just 6 months!!!
It's quite disappointing because it is very expensive for a fitted nappy, brilliant for the majority babies, but avoid if you have a chunky monkey

Very absorbent
Wednesday, 17 July 2019  | 

I use this for my 3 month old and have been since she was roughly one month old. The nappy is quite long and narrow, and even my tall skinny one month old had quiet a few poppers showing when in comparison, all her other birth to potty nappies were fully snapped to the tightest waste setting. Iím not sure if this will last, but itís very absorbent and I donít need to boost this at night. Very slow drying though, a full hot sunny day on the line isnít enough to dry this nappy, but I prefer reliable absorbency and natural fibres over quick drying nappies.
