He's come out in the blisters today so we've a trying week ahead of us. He's only 2.5 and still in nappies and I've already spotted a few actually in his bum. He's too little to understand not to scratch so what can I do to keep him reasonably comfortable? I've heard to give Calpol rather than ibuprofen? And I've also heard good things about Virasoothe and Poxclin - which one is better?
