When a parent with 1-2 kids sees such a big family, it's an unsolicited reminder of their own decision against having more kids. And (for many people) that is one of those decisions they prefer to keep walled off from reconsideration, which is easier to do around other small families, and harder to do when your pack of howl-at-the-moon kids is running all over town withholding external validation, lol. Fwiw I think your happiness with those trade-offs will increase over time, cheers.
