My pregnant wife with Green card status is stuck in India due to COVID-19, What are my options as she cannot come until she gives birth? [closed]

My wife is stuck in India since Feb 24, she's supposed to come on April 30th. But, all flights were cancelled including ours. There are repatriation flights, but, she is 32.5 weeks pregnant when the repatriation flights start running from India to U.S during next phase.

I am thinking my wife will come back to U.S before August 18th (she'll be outside for 177 days) after she gives birth at the end of July.

Can she go back to India after 2 months of staying in U.S to take care of our baby? (Meantime, my parents will be taking care of the baby). Will she face any more questions?

(I am a U.S. citizen and not worried about my kid as I can apply for CRBA)

Please be nice as we are going through a tough time staying apart like so many others.

EDITED for clarity:

1. Will she face any more questions when she comes back to U.S for the second time?

2. Does the 180 days stay outside U.S. for LPR applies for the calendar year or only for continuous stay outside U.S? Meaning, can a person with LPR go outside stay for 5 1/2 months, stay in U.S. for a month and go outside U.S. and stay for 5 1/2 more months?
