Buy different jars baby food and diapers. Place smear of one of each food into diaper (like baby poopoo). # each diaper and coordinated jar. Give everyone a sheet #'d 1-10, 12, 14 (whatever # diapers you are using) Pass diapers around and,everyone must try to guess what the baby ate and record. Whomever gets the most correct, gets a prize!!!!
