No.
IMO I’d far rather people were upfront and just said they didn’t want to.
i also think it would actually increase bf rates.
when I was bf other mums would tell me their tales of why they couldn’t/didn’t breast feed. A lot of it was lack of support or knowledge, or the expectation that they should try- and needed a “reason” to stop.
i’d nod along of course, but part of me would be thinking this is why people don’t bf. I was being told you can’t bf a baby more than 9lbs, boys cans be “hungry” and need more than bm, cluster feeding at night meant they had no milk, sucking hands meant there was no milk, they couldn’t tell how much the baby was getting, they weren’t sleeping through at 6 weeks so there was no milk…
like I said, a lot was basic need for someone to point out what they were experiencing was normal.
but a lot of mums might have listened any though well my baby isn’t sleeping through, maybe I don’t have enough milk, and consider giving up.
bf is hard. If you don’t want to do it, for whatever reason, don’t. But no one should have to justify to anyone either. Especially when you’re passing on incorrect information to other mums, however well meaning.
