This is a very personal choice and only YOU can decide what is right for YOU.
Imagine yourself in your 50's. What do you see for yourself. Do you see yourself still taking teenagers to high school events. Do you see yourself going to middle school programs or events. Do you see yourself going to teacher conferences. Or, do you want to be past that stage and hoping for your children to be bringing grandchildren to your home when you are in your 50's?
No one can tell you what is right for YOU. If you have a life goal and it doesn't involve still dealing with children under a certain age when you reach a certain age, then don't adopt the child. If you are having doubts, then it is a good indication that you are done with having more children. (including adopting more).
As for what age makes an "older" mom - that is hard to judge. You would get a wide range of answers from that. My husband and I both feel like we had "older parents". My mom was 35 when she had me. His mom was 34 when she had him. We both felt like we grew up with older parents. We felt like they just wanted to read their newspaper or books and watch TV instead of doing things with us or taking us places like the younger parents of our other friends would do. When my father would take me places, people would often comment that he had a cute granddaughter instead of daughter. We both had the same experience and we both agreed that we would have our family before the age of 30. At the age of 30, we were done having children. But, again - this is a very personal choice and at the end of all of it, only you can decide what you want for your future.
