Very adorable girls! Hope you can stop worrying about Sadie soon. I didn’t have quite the same situation, but my daughter was 6 wks early and in the 3rd % forever (OK, not forever, until around 18 months) and when the doctors would comment how it would be nice if she’d gain a little more, I always got a little obsessed, but dang my kids were not big eaters! Sending good thoughts your way.
First, they’re adorable. Second, Becky was talking up your book and now they are both on their way to my doorstep. Third, my kids got their first teeth at 4 months old. (Yes, I’m one of those people who sometimes reads all the other comments before I leave my own.) Fourth… okay, there’s no fourth. I’ll just tell you again how cute your girls are. And now I will go away.
