Are natural fabrics best next to baby's skin e.g cotton? This will mean, obviously, it will be damp next to their skin until you change them. Or is having a 'dry bottom' paramount, in which case you'd have a synthetic fabric next to their skin, such as fleece or minky.
When James was in nappies - he hated any wet feeling so we used fleece liners. We did briefly use disposable ones but they moved around too much and got all scrunched up - so were a total waste of time. With Eleanor - she's not been bothered - so we've often not used liners with her.
I think it's more important to have a breathable fabric next to babies bottom. Whether its man made or natural doesn't make too much difference - just so long as its breathable. Which is why we love our fitteds and wool the most!
We use fleece liners too. DS2 reacted badly to dispo liners but instantly cleared with fleece. I guess it depends on how your LO reacts to the wetness against the skin? If there are no issues then I don't see why not just have natural fibers close to their skin
I've been tempted by some Micro Diddy Diapers - they are microfleece outer and lined with cotton jersey. I reckon, they'd be very absorbent, but wet against baby's bum - so I'd need to use a fleece liner if I didn't want the wetness to be against baby's bottom. We've been using paper liners so far and LO has had nappy rash, it's hard to tell what from exactly.
I like microfleece for its quick drying properties (we have no dryer) but I can't help wondering if babies bottoms get hotter (or sweatier - tmi?) in microfleece vs cotton or bamboo?
I love our Motherease Sandys and Kissaluvs but they do quite a while to dry.
