When he was sick and miserable on Saturday I did the YMCA song with him and he tried to smile at me even through his snorfly misery.

This, oh, this. It's so adorable and heart-wrenchingly sweet when they still try to give you the reactions you expect, even when they are miserable and sniffly.

Hooray for communication and developmental milestones! Hooray for the YMCA and inspiring cuteness!
