“Just wait until you’re a parent”

This is probably the phrase I hate the most from my friends who ARE parents. I’m just 9 weeks pregnant, so although I am “technically” a parent, my baby is the size of a raspberry and can’t talk back or throw tantrums yet 🤷🏻‍♀️ but quite often friends come to me venting about their kids. Most recently...a friend of my husbands stopped by to pick up an air mattress to sleep on. This is because his 4 1/2 year old twins want to sleep in bed with his wife...so there’s no room for him. He sleeps on the floor with the dog next to the bed with some blankets and pillows. He also told me he and his wife don’t get any alone time because of this and his wife (who is recovering from surgery) gets no sleep because the girls are on top of her all night. So me, thinking he was seeking an opinion, suggested he and his wife tell the girls they simply can’t sleep in bed with mommy anymore. I told him just put your foot down, you can’t be a second class citizen in your own home. His response was “just wait until you’re a parent...the kids get what they want. You turn into a second class citizen the moment they are born”. So I smiled and said well yes you’re right I’m not a parent yet, I just want you two to be happy. Realistically, I’m feeling like their kids walk all over them. Those kids most definitely legit get whatever they want. Lol. But it’s NONE of my business so I let it go. I guess my point in posting this is to ask other childless couples how they stay neutral and unopinionated with your close friends parenting choices. Because you know we all inevitably will get the “you’re not parents yet” speech. And listen, I get it. Hindsight is 20/20. I just have a hard time not feeling inclined to share my opinion. Maybe I just need to practice silence. 🤦🏻‍♀️🤷🏻‍♀️🤰🏻
