This video is from march 15...the day before 13 months. He did this squeal business for quite some time. I asked Kyle do you think he'll keep it up long enough for me to get my camera...nah! But he kept going so I got the camera. It started as spontaneous squeals I think because he was pretty impressed with his skills of pulling himself up and standing at the ottoman. By the time I'm recording I think he's doing it for effect, but it's still kind of funny.
This is his official 13 month old video, riding the tonka.
