The Toddler Photo Limit

The Toddler Photo Limit (TPL) refers to the natural photogenic decay rate of any set of toddlers with respect to a given period of time.

T = Σ(ages)/(N * s)

Where T is the amount of time (in seconds) a photo-op will last. Solving for T, we sum the ages of all toddlers involved in a photo-op, and divide that number by the product of 'N' (number of toddlers) and 's' (number of toddlers who are siblings with other toddlers involved in the same photo-op). Note that as 's' increases, the value of T becomes drastically smaller.
