Requesting inlaws to quarantine before meeting baby. Help!!!!

Baby is due in August and I’m delivering in a city that’s 2 hours plane ride from where my in laws stay. I’ll be living with my parents about 2 weeks before my due date.

The country I live in has a very high number of covid cases and we expect to hit he peak in July. My MIL and FIL are 60+ and would obviously want to meet the baby - which I have no prob with. But I don’t want them meeting the baby without them doing a quarantine for 14 days! How do I tell them?!? Specially given their immune systems are extremely weak and so will baby’s and mine when I deliver. My FIL is not someone who will quarantine himself for sure but I don’t want them meeting baby if they are not ok with it, given I’m having this baby after a struggling for 4 years!

Any suggestions on how I can handle this smoothly?
