I am 40 years old. Is it too late to start a career in software development?

Hello all… not sure if I should make a different topic of this but I’ve read a lot of these posts from the top & got inspired to create a account and ask for advice along my path which is similar however a bit different.
I’m 37 have a 1 year old and another on the way in August or September. My background is in digital printing however, I’m working in Security to pay the bills. The kicker is that I have a petty/stupid misdemeanor on my record that I’m unable to expunge because of va petty laws. However I’m enrolling in a community college to become either a programmer or a software developer more so interested in the software developing field. Would this misdemeanor hinder me or should I just put my head down and go for it and get letters of recommendations along the way? Thanks for the feedback if any!!
