Well I decided to take a long walk with my son in the jogging stroller, I didn't use the car seat for the first time. So while I was walking the only way I knew he was awake was when I saw his spit bubbles... when it stopped I checked him and he was asleep. Then about 30 minutes of being asleep, I saw a big spit bubble.. I said "Are you awake baby boy?" He yawned and blew spit bubbles the rest of the way.. I said awwww in my head. I don't know why, I find him blowing those bubbles so cute.
