What is the best strategy

D. and F. bought one beverage box with 32 bottles for the weekend party, but one of their four children changed the content of one of the bottles that cannot be detected easily! To punish the children, they decided to permute the bottles and ask the children to find it again by tasting them until 11 days later! Unfortunately if one drinks from THAT bottle, he/she will be sick 10 days later for a week, but the children like to participate in the party! What is the best strategy for the children?
