Louis has done a poo both times I@ve put it on him and I've just been hand washing them which is working out soooooo great, I don't seem to have nearly as many nappies to wash!! I think it will be amazing when we go away and now wihs I'd got a 2nd pair mind you it seems ther's a few up for another order!!
I have only washed mine at 40. I think you could probably wash the pants at 60 but I know there are issues with the Weenees pouches and washing them too hot so I wouldn't want to put them through too hot.
