Chubbysan,
It's good to get infant or child below 6 to have the rotavirus vaccination, although it might be costly, around SGD180 for 2vax (oral type). My second son (now 18months) had it few months ago. Likewise to Summersun, I had an awful experiece with my elder son who got rotavirus last year, he stayed in hospital for 5 days, on drip, vomit (whatever in, whatever out) and diarrhear countlessly! It's very heartaching to see your child going through the suffer, so is better to prevent it from happening.
