So the book suggested doing an activity to demonstrate the difficulty of finding one little pup in a very crowded nursery. I got twenty cotton balls and put a different scent on each one. Then I assigned one scent per child and told them to memorize their *baby's* scent. Then I put them all on a tray and had them try to find their pup...blindfolded. It was a fun activity...lots of laughs...especially when Austin declared "I'm such a bad mother" when he couldn't find his baby at first. LOL!
Our list of scents...
dish washing soap
(And sorry, my memory fails me for the last 2.)
