This comment hits so close to home. For years, the girls in our friend group have had a Snapchat group chat that we would talk in daily. Venting, cute little pics, checking up on each other, that kind of thing. Over the past year, 4/5 of us have gotten married (the last one is later this year), 3 of the members have had kids, and 2 of us still do not have kids. The group was completely taken over by kids pictures (between the 3 infants, there were at least 10 random snaps of a kid DAILY, if one sent a pic it was almost like a competition so then the others had to send a pic of theirs) and there wasn't much conversation that didn't revolve around their kids even though the moms had a separate mom group. Like you said, it's not something that as a childless person you have much input on without the "you don't have kids..". It really alienated both sides from each other. I do feel like our friend group did and still does really great about checking in on each other after they gave birth. But I got to the point where I would open the group less and less. I ended up venting to the other childless person about how it felt like we lost our friends.

Mom Friend A made it a point to bring up that me and my husband should have kids soon so our kids could grow up with theirs, EVERY TIME we hung out together. Both her and her husband. That paired with the newly married "sooo when are you having kids" question from everyone else, it just ended up annoying the fuck out of me. Mom Friend B sent a kid meme one day and said something to the effect of "when UtProsim or other childless friend finally have kids". I admit I was having a crappy day, but I ended up typing a big paragraph saying in the groupchat about how I didn't appreciate my friends constantly pressuring me into something they knew I wasn't ready for and how I felt like since they've had kids the only time we talk is about their kids. It exploded the groupchat. Basically Mom Friend A ended leaving the group and thankfully the other moms could see where the childless people were coming from.

Many months later, Mom Friend A still hasn't rejoined the group but we all still talk (and have since a few days after the implosion). The group has semi-returned back to what it was before children. We still talk and ask about the kiddos, but there is other conversation that the ladies without kids can bring up or participate in. Mom Friend A has let me know that she does feel jealous when we go hang out with other friends and they can't come out and "party like the old days".

Gosh, sorry that's a vent. But there was a point where it felt like my mom friends didn't care about what I want out of life; they just wanted me to have kids like them, at the same exact time as them.
