Kids at 30 ?

So people are always giving me crap about how having kids at 30 is too "old" which I don't think it's old at all, my mom had her first child at 29 and her last at 38 which is me, and her pregnancy all went good so I don't understand why people are suggesting I have them in my 20s, like I want to be able to live my life and travel and get married and not have to worry about taking care of a baby while I'm young and be able to spend money on things for me and live in a nice house and everything else and then after all that I wouldn't mind having a baby when I'm stable and everything, I just feel like I'm getting pressured into having a baby young. I mean is it bad to have a baby at 30 ? Or ?
