So DD2 is just about to turn one and is finally showing signs of getting her first tooth. Previously, she gets horrendous nappy rash overnight and is very unsettled but with nothing to show for it. Now, she has the nappy rash but she also has eczema all over her back and tummy and its spreading to her arms. For the first time, her gums are swollen and you can see the erupting tooth just beneath her gum.

My question is, is the eczema at the same time as real, proper teething coincidence or can teething cause eczema flare ups?

TIA
