We've used Pampers since DS was born. He uses 4+ baby dry's now, but the packet we bought recently advertised it's new extra 'sleep layer' (or something like that). It's like a green layer in the centre of the nappy. Anyway, poor DS has had terrible red sore bum for a few days now - just wondering if it's the new layer affecting him so we've gone back to old style pampers that I found at bottom of cupboard. Anyone else noticed a change in thier DC?
