If they are 2 months early then they are probably 30-32 weeks, and maybe around 3 pounds (twins are usually smaller than single birth babies). If you find out any more information, or just want to ask me any questions about what may be going on in the
NICU where they are, feel free to ask. I'm not sure what's going on with your nieces specifically, and of course every baby is different, but babies after 27 weeks do much better than those born earlier because that is when lung development takes place. They'll still have a long road ahead of them, and I pray they do well. I'll keep you all in my thoughts. :)
