My mono/di twins are showing a 23% growth discordance. The good news, I guess, is that they don't suspect TTTS at this point because fluid levels and blood flow look good. Baby B is still growing, just consistently smaller. Doctor suspects selective growth restriction and said they'll just monitor closely. Does anyone have experience with this? I had never heard of it until today. I made the mistake of googling it when I got back from my appointment. I'm just trying to tell myself that chances are very good that I can keep these little guys in for several more weeks even if things progress.
