Choosing a probiotic for your child can be challenging. Many probiotics are creating with adults in mind rather than children. If your child does not have a dairy allergy then you can try milk based kiefer. If however, your child does have a diary allergy like many children do, then you can try growing water kiefer grains, or you can try giving your child a smaller amount of a probiotic created for adults. Another option is to ask around at whole foods or to ask a chiropractor or a naturopathic doctor for recommendations for probiotics for children.
