Wool covers are amazing! Comfy for bubs, only have to wash every month or so or when soiled and wayyy easier to put on a rolling whingey baby than a snap on cover. We use these over out preflats + boosters.
I was definotely hesitant due to the special wash routine but it's super easy. The only issue I've found is they're much harder to get poo stains out of due to the cold wash only requirement.

Love how water resistant the wool cover has been and has kept my bub dry overnight! Highly recommend

Once I figured out how to look after and lanolise my wool covers (it’s literally so easy after the first time you do it) wool covers have made night nappies so so so easy!!!!!!

I love these, haven’t had any leaks. They will get quite damp if the night nappy isn‘t boosted enough but work very well if it is. I bought a medium and a large as I was unsure about sizing and worried my 5 month old baby would outgrow the medium quickly. They actually both fit well, there’s a lot of stretch so I think the medium will last a while, and while the large is clearly a bit oversized it still works just as well at preventing leaks - it just sits further up the tummy.
