I was just wondering - the combination of baby with bad eczema and nipple-mangling talents is something that Belfie had years ago too. From memory the diagnosis with the benefit of hindsight was that the eczema was symptomatic of allergies in general, and these allergies made it hard for her little guy to breathe through his nose - meaning that he would be constantly slipping and sliding and coming off and on and generally being rather mean to his Mum.
Do you think S's nose is blocked at all??
