hey everyone! so I'm due in March and we live in Oklahoma. my family lives in California and they are insisting that we fly there so everyone can see the new baby and even offered to pay for our tickets. while I'd love to do that, I'm worried he will get sick from the airport. I plan to babywearing and breastfeed and we are doing no vaccines whatsoever. at what age would it be a bit safer to fly with our son? I feel like they are so fragile as newborns
