I have a running 13 month old….I’ve lost 10 lbs since he started walking (seriously), from chasing him around all day!!!!! My older son got 2 guinea pigs for christmas and wants one of those plastic excersize balls for them to run around in…..and all I could think of was “I wish they made them toddler size!!”But he doesn’t talk very much yet, so he’s a quiet little tornado!
