Before Use: Because Smart Bottom's cotton fabric is so pure, it still contains natural oils and will take several washes before it is ready to use the first time. Smart Bottoms believe it is much safer to wash your nappies a few extra times than for them to strip the fabric with harsh chemicals. It typically takes 6-8 washes to fully prep your Smart Bottoms nappies. Before you use your nappies for the first time, check to make sure they are ready by pouring a small amount of water on a dry nappy. If the nappy absorbs the water instantly, it is ready to use. If it takes even a couple of seconds to absorb, it needs a couple more washes.

Washing: Wash every 2-3 days. Prewash cycle on warm, followed by a main wash cycle on warm or hot (60deg). Use the amount of detergent recommended by the detergent manufacturer for your load size. Do not wash over 60 degrees.

Do not soak in anything other than water, and then only for 30 minutes. Do not use bleach. Do not overexpose to UV once nappies are dry. Bring them in from the line on hot summer days.

I am actually quite surprised I like this nappy. Initially I was a bit hesitant as it looks so trim and the inserts look quite thin. I like the fact that uses natural fibres and is organic. I also read that it does take a couple of washes to get to maximum absorbency as the fabric is not pre-treated. Even then, after only using it for the first time, absorbency was great for my average wetter.
The fit is good and the nappy is nice and stretchy. My bub is 6kg at the moment and I have not had any issues with fit. The rolled edges on the leg casings do not leave any red marks on my bub. I have not had any leaks so far. I also love the rover print which is the one I have.
