the poster who has never discovered something seemingly random that they do which is considered judge-worthy or terrible by another poster?
Leaving aside the traditional topics for conflict - breastfeeding not enough/too long, co-sleeping/controlled crying, formula - which people have very strong opinions about, the amount of stuff I've stumbled across where someone (or more enlighteningly, lots of posters) which is considered weird or just plain wrong by other posters is amazing.
Clothes (not babygrows) on babies. Not washing you towels regularly enough or washing them too often. Bottles for babies over 1. Not washing your baby's clothes before they wear them (that was a spectacular bunfight!). Forward-facing pushchairs. Playpens. Pureed weaning. Wearing shoes in someone's house. Owning a toilet brush.
Is there anyone out there who has yet to come across an odd thread that hugely judges something they do?
