Factoring in your tolerance for focus and how much time your child actually needs to get her tank full, I have found that twenty to thirty minutes is usually plenty in one sitting. That’s enough for the child, but it’s also when you will run out of steam for being super focused with what she is doing. That’s when the holy-shit-I-can’t-make-another-Play-Doh-snake starts to sneak in. Your to-do list starts to beckon. That’s when you call it quits. Anything after that point is going through the motions.
