Do you think it could be cradle cap? On the US version of babycentre website it describes something similar as "6 week rash" which is apparently common in newborns but haven't found anything silimar on any UK sites.
He seems ok, aside from wind/reflux for which I have given up dairy/onions/garlic temporarily to see if that makes any difference.
Would be grateful for any advice, my gut feeling is that it is nothing to worry about, but don't want to be a crap mum in case it is something that needs treatment...!
