My son has stage fright

So far we haven't been able to capture any of G's tricks on video. It's like the minute that camera is on, he forgets what he's supposed to do. Today my mom called and left me a message telling me that G rolled over from tummy to back. (I missed it! So sad!) Hubby and I tried to get him to do it again, but after 6 minutes of just watching/videotaping him fussing on his tummy, we gave up. Hopefully we'll have better luck tomorrow.
