Squidipa - hey just had a thought about the purple blotchy legs. A friend of mine's baby had purple blotches that came and went one night. She ended up taking him to hospital because the MCH advice line suggested meningitis. When she got there he had a great big fart and that was the end of it. No meningitis, just wind!! So perhaps it could be wind or even constipation? What's his poo output like? What is the consistency?
