Agree with you totally. I think at times I have had disconnects with friends who didn't realise what I had on my plate as a parent, and I was oblivious to what a bore I might have been, but the key is coming from a position of love, having good communication, and that lens of compassion.
I have gone back to the OP to see if I missed the point a bit, and I was interested in how what they actually said was "when I am with them and have my DS" rather than "I am only with them with my DS", and it occurs to me that frankly sometimes that is how it is when you first have kids, you become a package deal and eeking out a bit of adult 121 time gets tough.
She didn't say that was the case though, just that the friend has commented on how they are consumed when together with the child, and you can't just lob em in the corner and fully focus on martinis if you don't have a babysitter for the day.
Then we have a whole trail of angry people complaining about parents who think their kid is a little prince who everyone should be enthralled with! I get it, some people are awful, but that isn't actually what she said and she seems to have been tarred with a rather broad brush here. It feels a bit vitriolic, when as you say, empathy, acceptance and understanding are pretty key.
It cuts both ways exactly as you say. I remember going to a school reunion planning meeting with a babe in arms and feeling a real vibe from some attendees that I had the temerity to bring a boring infant to the discussion (I wasn't planning on bringing him to the actual event, which was shit because there is a reason why you lose touch with some people 😂). I definitely did lose empathy for the childless/unchilded/childfree friends at that meeting. I thought they were a bunch of dicks. Time moves on though, and I think they are (mostly) pretty awesome now. Some of them went on to have kids and some did not.
We just weren't aligned at the time.
Thanks CrazyGoatLady I really appreciate your perspective!
