Ugh. I'm also dealing with this.
I also HATE the "you just wait... insert negative thing here" comments. Especially rude from people who haven't been pregnant themselves so have no effing clue as to how difficult the day to day can be, especially if your pregnancy isn't the easiest ride... and hearing such obvious statements about not getting much sleep or "never having a life again" or whatever is so mentally hurtful. Like, WE KNOW, but Jesus, you just asked how I am and I slipped that I'm tired, say something supportive instead of grinding down what little mental energy I've got left!! Ugh. Anyway! I ignored despite wanting to slap that bish...
I've found my tolerance levels in pregnancy are borderline zero!!
I've ignored most comments about advice, most of it is outdated anyway and the only people who have given great advice that I've taken on, have given it in such a way where it didn't feel like it was forced upon me, so I was much more receptive. Stuff like, "oh the Heartburn... I remember, I used to take xyz, it really helped, if you're still steuggling give it a go" And left it at that.
Usually recent mums have been the best, because they get it, they also have been super helpful and yes, while they say it's hard, they've focused on the lovely parts to motherhood way more than the less nice parts, which I've really appreciated.
I've come to realise that there's always going to be those people who want to thrust their two cents onto you, but like many people say, ignore.
My brothers x wife cornered me the other week, I usually avoid her. She's had two kids, both 18+now. She said to me, in a condescending way "oh, I DO hope you don't get postnatal depression because it's SO HARD and it'll only get harder" said in this relly bitchy tone like she wanted me to suffer. (She's not the nicest person)
I rolled my eyes so hard they almost popped out. She's quite narcissistic so rather than engage I just walked off!!
Hard, because I want to say something, but I found I'd rather save my energy than waste it engaging/responding.
Sorry about my rant.... obviously it was bothering me more than I realised and i let it all out!!!
I'm sorry you're dealing with it too.
