You never know when your kid is going to surpise you with something they learned. Nolan isn't always very verbal, but he's obviously taking it all in. Today he surprised us with.... animal sounds! He will accurately make the sounds of a cat and tiger, and sometimes will make a whimpering dog sound. I managed to get "tiger" and "cat" on video before he tired of the game.
You can also see his "selective hearing" here- this is when we're not sure if he is not quite hearing us or just ignoring us!
