What do you older mothers think of this?

I saw this on my FB and it didn't bother me personally because I'm extremely self-driven person that believes my personal goals come first before I start a family. Even if I get to the point where I'm having trouble having a kid at the age of 35, I do want to adopt. I'm 24yrs old right now and I can't see myself with kids. But the girls that posted this were purposely making fun of those who want to wait. (They are my age and already have up to 4 kids). I know someone that has been struggling to have a kid and she's around 36, but she's been trying since she was in her 20s. My older sister is gonna be her surrogate mother and I'm so happy she will have a real chance of being a mother no matter what age she is. I just want to know what you girls think.
