@ThisOldThang They do, in a lot of places - or did. It's been strongly linked with cardiac issues.
Breastfeeding would be far easier if people didn't stare/comment.
To be fair, I was worried about this - mostly from posts here and on Facebook - but in 2.5 years of feeding, I had one weird interaction. That was all. And probably ten/fifteen mums coming over to congratulate me or say well done for feeding in public, etc.
I had a horrific breastfeeding journey; it was agony until 9 weeks and there was no support as to why. The midwives advice was well-meaning but shit; I didn't have the supply to pump, and we were pushed towards formula. It was HARD to reverse that.
In my NCT group, 7/8 breastfeed, but 3 didn't feed in public - they'd use wearable pumps all the time instead. Once the babies were 8 or so weeks old, they stopped feeding completely and bottle-fed. 5 of them stopped feeding at one, only 2 of us were still going at 2. For most of them, they stopped to TTC. The other one that stopped recently stopped because she's pregnant.
It's a tough place to be. The one who formula fed had to, and I know she feels constantly guilty about it, and wonders if it's impacted on her bond with her daughter. I don't want to make anyone feel more guilty, and it's difficult to reach the people who would never have naturally considered breastfeeding - like me, before the NCT, if I'm honest, I'd never seen anyone breastfeeding or considered it - and reaching people who are very sensitive to breastfeeding messages because they really wanted to breastfeed and couldn't for any of a variety of reasons.
