Feeling left out of those mom groups

Does anyone else feel like if they only have one baby that they’re not accepted into the “mom” group like I feel like just because I’m a new mom with one baby that I’m left out.

It’s just like when before you get pregnant and they say “just wait until you’re pregnant” then you’re pregnant and it “just wait until you’re close to due date” then you get there and it’s “wait until you go through labour” then you have your baby and it’s “wait until they’re a toddler” wait until there’s more than one”,”wait until they’re 6”, “wait until their teenagers” like ffs.

I just feel like yes, I haven’t been a mom as long as some other people, (not for lack of trying- I had 2 losses) but I’m just as much a mom as anyone else and I just want to feel included.

Maybe I’m crazy, does anyone else feel this way?
