I used to watch them a lot. But we haven't had cable in almost 3 years, so it's been a while since I have. I watched it a lot when I was pregnant with Cora, but after, I thought all those things you did, and just couldn't. Luckily I didn't have much of an opportunity after she was born. I agree with Dee, just stop watching.
Of course, on the random occasion I have seen it in the last year, it's brought up fond memories of Erin's birth, so it'll change with time.
That first birthday is hard. And don't be surprised when you're a little sad at the first birthday of the baby you're pregnant with now. The contrast will be more stark.
You'll get through it, and everything will be okay.
