Don't listen to them. Both my great grandma, and grandma had kids in their late 30s/ early 40s. Some of my uncles had kids in their 40s, my mom and dad had kids in their 30s. You wont be a senior, my uncles kids are almost adults now and I don't look at him as a senior at all. If I have kids I'll also want it to be in my 30s. Enjoy your family ❤
