Why choose not to breastfeed?

[MissBax]

I work in healthcare and have just been on a breastfeeding workshop as part of my training. I knew the benefits of breastfeeding for mother and baby anyway, but couldn't believe just how incredible it really was!
I was just wondering what people's reasons were for not breastfeeding? I'm not asking about health reasons or those who have suffered abuse etc. But just wondering why some women simply choose not to?
I'm not being a GF either before anyone offers me a biscuit 😉 just genuinely curious why someone would choose to bottle feed?

I used follow on milk for the first year and I was pleased I had when DS1 got a bad case of tonsillitis at 18 months and stopped eating for weeks.

He lost 2 1/2 kg by the end of it and I shudder to think how bad it would have been with just cow's milk.

I am thinking strongly in favour of FF baby when it comes.
Before anyone flames me or says I'm unreasonable I had a horrific time with dd. Milk didn't come in for 3 days, I found it really hard to get her to latch and then horrific mastitis and there was little to no support easily accessible in my area at the time. It left me mentally scarred and the thought or trying it again absolutely terrifies me.
Dd was FF from 1 week as per recommendation from health visitor and she had no issues.
