Any suggestion for a OTC probiotic for a 1 year old?

You can get Blackmores kid probiotic from Guardian. It is a trusted Australia brand. It has a very good taste which kids will like and it is suitable for kids who are lactose intolerant. I read that it's suitable for kids above 2 years old. http://sg.theasianparent.com/protection-from-illness-blackmores-kids-probiotic-powder/2/ For younger kids, they can also get probiotic naturally from food such as yogurt!
