Social worker with a felony?

I plead guilty to Attempted Child Neglect in 2008. Long story short a minor child who was in my home shook my baby and dropped him (why nobody will ever know) while I was in the kitchen and he was resting in his room and I was arrested MONTHS after the situation and told that because I was the only adult in the home at the time I am responsible for the crime that took place. I was scared and wanted out of jail and took the first deal offered which now has left me with a felony on my record. After witnessing first hand how the system sometimes helps people and other times screws people, I have a great interest in working in this field to help people and children. I do have my child and there was 1 woman who worked for CPS who was on my side from the start and even supported me while in custody. She went above and beyond her job for me and I admired that. It truly inspired me. I have my child and he is doing great but times do get hard due to the jobs I do not qualify for because of my record. I do have a job and have been there for a while but I want to go back to school to further my education for a better future for us. I have been doing a lot of reading while most of it seems positive for my particular situation but then I do run into some things that throw me completely off. I do plan on reaching out to my old case worker for any information as well but all I really want to know is if this would be beneficial or a waste of wishful thinking. I know I need to be licensed as well and I live in Nevada but can't seem to find the exact requirements for this as far as felonies.
