Oh my gosh, 26 is not later in life! Wow. I think of going back to school and I'm 40! You are no way near later in life, that's your clock telling you that I bet.
You sound set on the baby and as well you should be. But as an older woman, who has lived a bit, please, please don't think anyone is going to take care of you. Your man is really great to offer and be a provider as some men like to be, but there are no guarantees. I'm glad you are getting a profession and looking after that, but stand proud in it, cause you may have to look after yourself with a baby in tow one day.
Other than that advice from an oldy goldy that has watched friends marry, have babies, and divorce way more often than not, take care of you and enjoy being looked after at the same time. Good luck
