Probably breastfeeding. I thought I would breastfeed for a year because that's what my mum did. Ended up BFing DD1 for 3.5 years and tandem feeding! A younger me would have thought that was really odd and gross.

Not smacking or doing time out. That's what my parents did and everyone I know. I thought a little smack was ok and a way to learn. Then I had these kids and realised there must be another way because I'm not hitting them!

I thought 'my kids will never eat on the lounge, in the pram, in the car' Umm...rule broken as soon as they could eat.

Mostly I just didn't realise I would love them so much and want to do everything the best I can for them and want to find out what that is, even if it means going against the grain. Before I had them I just assumed I'd follow along with what my mum did.
