New Tricks

Olivia is growing so fast right before our eyes!  In the past week or so, she's started laughing, rolling over and started doing this:

She's mastered this (what is it called anyway? Spitting? Rasberry-ing?) and does it all the time. 
I have yet to get her laughing or rolling over on camera.  I have to really work hard and look like an idiot to get a laugh from her :).  She has been rolling over a lot during the night, which wakes her up, so I have to go in a couple times and turn her back and cover her back up.  I can't believe she's almost 4 months old already.  But it's so fun to watch all these milestones that happen so quickly!
