I'm turning 30 soon and I feel pressure to have a baby
Why do you feel the pressure now?
Because having babies is all people think about these days
I think that your family could be a part of your reasoning. It is okay to not want to have kids. Kids are not for everyone.
My family would see me as a disappointment if I don't have kids by 30.
You should tell them that your generation is different than theirs. Not only is your generation facing crippling debt and stagnant wages but it's even harder to buy a house or to even get life started so they should mind their own business.
