Well, I think you can only ask her if she's sure she'd like a caesarean and that it's six weeks of pain versus one day(ish). That's all you can do. Sometimes people have to make their own mistakes - as you said, it took you three births before you had your perfect one.

On the breastfeeding, your sister sounds like she can give her both perspectives - remember, it's not always easy for everyone so I would be hesitant before saying that.

It sounds like you have doubts whether your sister will be a good mum. Even more reason to try not to get her back up now and save your advice for REALLY important stuff.

I had to bite my tongue for a very long time with my own sister and try to establish a good relationship with her so that she would actually listen to me when I told her that feeding her 5-year-old son cheese sandwiches or hot chips for EVERY meal (I'm not kidding) was really not good enough and she was going to have to learn to cook because he was malnourished with v bad eyesight. If I'd had a go at every decision she made up to then, she simply wouldn't have listened to me but because I chose only that battle, it did have some effect. Maybe I'm reading too much into it, but It sounds like bigger things might come up FionaJill.
