I believe nursing mothers exempt, but interpretation varies. There are a lot of different shades - just as there is with Christianity.
i was once in the dentist and a young man said he could not have treatment in ramadan - even dental mouthwash was not allowed to pass his lips!
As a school governor i was always pleased when it coincided with school holidays (like this year) - kids not on top form in school, and then wanting 2 days off for EID. (attendance stats suffer if you have say 1/4 muslim)
It is hard on the women when it falls in the summer though - unlike the middle east where they do not have our long days, in Uk they have to get up about 3.30 to make breakfast and then they cannot break their fast until after sunset - at which point, large meal and lots of washing up! Fall into bed about midnight, and before they know it, off they go again. I worked with someone who was shattered throughout ramadan for this reason.
