When is the earliest you traveled with your babies?

I am getting ahead of myself here but just wanted to entertain or just ponder on the thought.

I know babies get their first shot of vaccines at 2 months but not much after that. I want them to be as well protected as possible with airport germs.

My travel plan would want to fly out to where family is for them to meet the babies maybe around 6months or around that time frame. Of course, probably consult their pediatrician and unsure how the health of my babies will be as well since they are to be here sometime this month.

Let me know of advice! 😁
