6 weeks and past the "due date"

Six weeks old yesterday, which was also the twins' due date. They are still sleeping a lot, but getting more alert and staying awake for longer stretches (often in the middle of the night). The last few days they have been in a feeding frenzy. They are only lasting two hours between feedings. Forget about making it fours at night - doesn't happen. I think it's a growth spurt. But they are both doing so well still and continuing to be adorable. :)
