DD is a huge wetter, and the only thing we've found that works is 2 flats and then a wool cover. However, after the 2nd night of our heatwave, DD woke with the worst nappy rash she's ever had - we had to get an anti-fungal cream to clear it up, and she's also been gonig to be in a disposable. Its a lot clearer now, but I don't really like having her in sposies every night. Do you think it was the wool cover, and with her getting so wet, the heat just made an ideal environment for the nappy rash? What else could we try?
