Jumping humor

So the best thing lately with Aidan is how he finds his brother so humorous. Dylan just has to do some little silly thing and Aidan cracks up at it. For instance today when Dylan and I went to get Aidan after his nap we found Aidan holding onto the side of the crib and sort of practicing jumping/bouncing on the mattress. So Dylan held onto the railing from the outside and started bouncing and Aidan was cracking up at it. I wanted so badly to get the video camera but knew once I got back with it it would all be over.
