just wondering how often it happens or I should expect my twin boys to get sv? they are 2 and go to childminders 2 days a week. 4 children go in total. they had gastroenteritis around their first birthday(lasted 2 weeks) another sv April of last year( lasted a week). then recntly in November a mild case lasting 2 days. do they get things less and less as they are older? and does the duration shorten? sorry for all questions. were in the UK x
