My partner is the youngest of 5 kids. I've noticed the one he seems to get on best with is a brother 10 years older. He's got a brother even older again so very big age gap 'tween my partner and his eldest brother. Brother closest to him is ; years older but they don't really socialise much - interests and inclinations are completely different.
AIBU to think of you have 5 it's best to have a big age gap or better close together ?
