Jet's much better after the weekend. John and I are still relatively sane and not too sleep deprived. The nights were pretty horrible until we figured out the propping up the baby trick so he could breath for more than twenty minutes at a time. Whew.
Jet crawled forward for Joan today. Five hops forward, and then she couldn't tempt him to do it again. He was going for Haley's toy. I really do think competition among siblings is the root of all major progress.
