I put green food coloring in my 3 year old daughter's milk cup. When we poured the white milk, it turned green, and she was bamboozled.
I switched cereal bags so when we poured from the cheerios box, out came great grains.
To a 3 year old, this is hilarious.
Speaking of her (and her little sister), they are the wild cards in my early FI plan. I'd love to pay for their college, but I don't love the idea of having to increase the liquid assets from $750k to $1M. Still don't know what to do there.
