Instructions on taking the Probiotic and Placebo Powder!


To take the probiotic or placebo powder, your child should open the packet, tilt his/her head back, and pour the powder onto his/her tongue. He/she should then drink some milk (a half cup or more). Another option is to take the powder by mixing it with a small amount of ice cream. Try to give your child the probiotic/placebo at approximately the same time each day.
