Love having 1. Especially now DD is 16. We definitely made the right decision.
I have 4 siblings. Dh has 2, so it's not like we don't know what it's like. We love our siblings too, but 1 was the right decision for us.
We can pursue lots of activities we couldn't have done with 2 or more.
I also appreciate it as I've seen other families who's kids bicker, adult siblings who don't talk to each other etc.
We have a calm peacefulness in our merry gang of 3.
We do have a larger living extended family of cousins, uncles etc.
DD is not a brat, or lonely, or shy, or any of the other stereotypes people with more than one child constantly try to profess🙄
I wouldn't say you're right or wrong wanting more than 1, but this is just my experience.
