Baby B not doing well

Almost 20 weeks pregnant with twins however just went to another MFM for another opinion and didn’t get good news about baby B. Baby B is at least 4 weeks behind and in 1st percentile growth. He said his heart is too big for his chest. He said more about Baby b’s abnormalities. His heart rate was over 140. Doc said his chances of survival are low. 😭😔😩

Then Baby A is fine and measurements are where they should be and his heart rate is over 140 too. No

worries on him at all.

I’m so heartbroken! 😩😭 For those that have dealt with this or going through it how are you dealing with it?
