We had that bug the week before xmas, luckily I got it when Louis had finished, I used a mixture of dispos and cloth as it was horrid Hope you are all better soon!
I used sposies too, when my LO had a diarrhoea for the past two weeks. For first two days I used cloth, but then I got really sick and tired of hand prewashing a pooey nappy 10 times a day. I felt guilty...and relieved We're back in cloth tomorrow as her poo is slowly becoming more solid again and it happens only once or twice daily now.
