We are nearing the end of the worst case of HF&M. Older three DS's have all had it but 11month old has had and still has spots now and its been just over 3 weeks and 3 years old will be three weeks on Wednesday. Both just had the one day of fever then spots that just keep coming up and new ones come up every 5 or 6 hours it seems. Poor 3 year old has lost a whole layer of skin from most fingers and toes from the blisters merging. Dr said usually lasts 5-7 days - i guess at least we're above average in something oh and DS's started in his mouth too - I imagine if it is HF&M they will have more noticeable spots elsewhere by morning. Hope not for your sake!
