He has so many Mason-isms that make Dash and I laugh every day. Some of our favorites...
His karoke 'singing' into his toy microphone
Talking into everything like it's a phone, from grilled cheese sandwiches to blocks
Playing his bottom lip like a guitar
His air kisses
He nods repeatedly when he is babbling to punctuate what he is saying
His game of pillow plopping, where he pulls all the couch pillows off onto the floor and throws himself onto them, then rests his little head (actually, not so little - 75th percentile)
I can't believe how fast he is growing up. It just keeps getting better and better, as we get to know our little boy.
