Lea - the red raw nappy rash seems to be directly related to those explosive runny poos. I guess the only thing you can do is to change him regularly (as soon as he poos) and slather his bum in nappy rash cream. The thicker and zinc based the better as it'll stay on longer and the zinc helps in the healing. Nappy off time is great for it too...sunlight is a great natural healer. Oh, and just keep an eye on your diet and make sure you're not eating anything too rich, spicy or acidic.

I know there are a few threads floating around about troublesome nappy rash and loads of remedies and ideas on how to get it healed quickly. Glad we can be of help!
