Keep track of your children with the Giggle Bug toddler tracker. The cute little red or yellow bug clips to your child’s backpack or clothing; press a button on the separate fob and the bug emits an 85-decibel beep and its eyes blink until you deactivate the unit. It has a range of 75 to 100 feet and runs on three-volt coin cell batteries. It costs about $20 at Safe Beginnings, Bippity Boppity Baby, and at Familyonboard.com.
