Leg lefts and a whole lot of compassion

So, in a desperate attempt to lose each and every dreaded pound that I gained with my pregnancy, I've started doing two workout videos...one is Taebo and the other is a horrible, straight from the Devil leg lift video. Brayden thinks it's great to "exercise" with me and it's good for me because I laugh at him the whole time and somehow makes the video seem not quite as grueling. There are several times in the video when I just can't help from repeating, "oh, it hurts, it hurts". My son of tremendous compassion gets a terrified look on his face, stops what he's doing and always kisses my legs exclaiming "it's ok mommy- is it all better now?" Somehow the pain always seems to diminish.
This morning, he did something new and it melted my heart. When Brayden was a baby, he had acid reflux and he would scream for hours at a time. In order to not go crazy, I made up a song and sang it to him each time he cried. It was as follows:
"It's Ok, It's ok, mommy loves you anyway" -Repeated over and over
Well, this morning, in my pit of leg lift despair, Brayden sang out:
"It's Ok, It's ok, Brayden loves you anyway" and gave me the biggest hug he could muster.
I knew he remembered the song from because I've often overheard him singing it to himself or even to Bryce... but today was the first day that he changed the "mommy" to "Brayden" - like he REALLY understood what he was singing! Gosh, I love that kid!
