Toddler Tinkerings: Eye Spy Bottle
An Eye Spy Bottle is simply an empty water bottle (or other bottle) filled with rice (or other filler) and various small objects. Your child then turns the bottle, searching for the various items.
I kinda assumed the older kids would be more interested in this activity than my toddler, but it has been the other way around.
Faith is 20 months, and she picks this bottle up quite often. She turns it until she finds the balls (marbles).
