@purbal And so it begins. . .as soon as I announced my pregnancy with my first, there were so many unwanted comments. I'm sure no one meant any harm but it was still very irritating. I completely understand where you're coming from.
It's very strange how, as soon as you are pregnant, people feel like they are automatically invited to, in many respects, a very intimate part of your life. DS was born at 6lb 6oz and has followed his centile chart quite steadily since. There's been constant comments about how "scrappy" he is and frequently repeated questions on whether I was breastfeeding, which I felt was some people's passive way of suggesting I should formula feed instead. The amount of times I would have to answer the same questions about breastfeeding were VERY annoying. It's not a community choice!
I also get on with my MIL quite well but she would ask all sorts of questions about the birth that I personally felt uncomfortable talking about. This time around, I'm fully prepared for the annoying comments.
In terms of referring to your DC as lazy, maybe a lighthearted "not lazy, just content" response with a smile should shut them up.
If you have instagram, The Positive Birth Movement post some relevant stories and posts about induction and body autonomy. It's quite affirming in that it is our choice how we birth and we shouldn't feel cajoled into making decisions against our better judgement.
