Husband wants to attend attend out of state funeral without our 4 mo old?

Husband’s aunt passed away, whom he was very close with.

To clarify, it’s not out of state for us- but the rest of the family members attending would be flying in from both east and west coast states.

I know he can wear a mask and use sanitizer but he would be driving 5 hours to the funeral. There will absolutely be hugging and crying (snotty rags). I do want him to go, but I’m worried about him bringing home Covid in particular. I suggested he quarantine in our guest room after the weekend but based on his answer (“I just won’t go”) I think he doesn’t want to be separated from me and baby.

Additionally- His mom wants to visit baby for the first time during her trip to for the funeral. This is significantly earlier than we were prepared for. Coming for CA to FL is a pretty long flight and would likely have a lay over to our specific area. I floated the idea of meeting outside and not holding the baby but he isn’t sure she would be receptive to that (and I’m not sure he would help me enforce it).
