So we have reached viability, with a theoretical 50% survival rate if the fetus was born today. Happily, he doesn't look like he's going anywhere anytime soon. I'm still feeling pretty good. I have a lot of heartburn, and I can't really bend over any more, but I am still able to sleep reasonably well.
We've even started doing some shopping. There was a special at the supermarket last week, so I bit the bullet and even bought some diapers. We have started talking about names, and looking at cribs. With every day that passes, I am feeling less terrified of disaster, and more excited about the future.
