I’ve certainly seen the issues with the first born. It’s a strange phenomenon for sure. Some places you see it and some you don’t. Even kids that are raised well in the same household end up having things like that. I think a lot of it is nature versus nurture. Some aspects are inherent and others are learned. Hopefully your daughter hasn’t learned this from that lovely mother in law of yours!

Hopefully if I have another kid in the future my son won’t end up being that style but the age gap would be a lot higher!
