Spent a lovely weekend with friends who have twin toddlers. On Sunday night their mum rang to say they had come out with chicken pox and had my dd had it. She has so I wasn't to worried. Yesterday DH got an email from twins dad saying they'd found out that they've actually got Hand, Foot and Mouth Disease. No idea what this! DD spent yesterday with a high temperature and generally being very lethargic. Is it a coincidence? Any info greatly appreciated.
