I have mentioned this activity a few times - about an older infant or toddler sitting at their little table with a set of toothpicks and a jar of varying kinds.
Not everyone has baby food jars - some of us make/made our own ;) So an alternative?
NOT this (awesome spice jar from IKEA - lots of uses - this one ain't it)
|Toothpicks go in, but don't all come out.|
