"We had just stopped off at the local picnic site with our 13 month old grand-daughter Lucy, when my wife spotted her tucking into a 3 day old, fairly firm dog poop. Lucy started crying when we took it away from her. But it seemed to help ease her teething pains, so we let her suck on it for the rest of the day. My wife now takes a dog poop with her when babysitting to keep Lucy amused."
