Am I selling myself short? Advice?

I have experience as an ABA therapist, a pre-k teacher, and a sensory motor counselor. I am starting my PhD this year in psychology and I really want to work in Academia. I feel like none of my work experience matches up with this. Right now I am a nanny making over $40k a year and it’s a really really lenient job which is why I took it. I also took it before I had my BA so I had limited job options that paid as much anyways. However, my job ends in August and I don’t get my MA Until December. Therefore, there’s a big gap and we need my income to make it. So of course, I’ve found myself accepting another nanny position after this is over. Even though I’ll be a PhD student 🤦🏻‍♀️ I’m stressing about if I’ll ever get out of this childcare/child development cycle and into academia. I don’t even know how I’ll get a job with my masters in academia with no experience. I’m just stressing out. Am I selling myself short by accepting another nanny position? Any advice from people who have been through something similar?
