Puzzle-time

Micah completed his first 100 piece puzzle today.  This was not done in one sitting, though.  This puzzle was something he had to come back and forth to when he felt like he was ready to work on it.  Noah really wanted to help his brother, but I really wanted to see if Micah could do this.  After several attempts at getting him to sit and focus, he did finish and he was very excited.  When will he do his next puzzle???
