I don't know why, but Mark has discovered a way to make Riley stop crying that works every single time. She could be hungry, she could be tired, she could have gas, it doesn't matter, when he does this, she is silent...
Now, "what is that?", you might be asking yourself. Basically he walks around a lifts her up and down, up and down. We call it the baby push-up. It's magical. No really, it is. I don't know if it's the motion, or the view of the ceiling, or the combination of the two, but she loves it!
