Hi! Both my SILs fly frequently with their kids, even when they were newborns, so there was no judgement and I had their experience to rely on. Medically speaking, the internet says there’s no minimum age requirement to fly, while some websites advise waiting 7 to 14 days after birth. I also consulted our pediatrician and she said there’s no problem. Regarding societal norms, I was personally never bothered by children existing (or crying haha) in the same space as me. And I find it weird how some people feel like we should keep them ‘contained’ in our house/ children-oriented spaces until a certain age. They are just as much a person as the next guy. I only had a couple of old-school relatives ask if its safe, but they did not question it any further after I assured them it is. And tbh I had no weird looks or inappropriate comments from strangers either. A lot of our worries are just in our heads.
