Job fairs/interviews with baby ? I feel stuck

I have absolutely no family close by where i live my husband is incarcerated I barely have any money as im just getting by with bills my son and my dog thank god but genuinely im looking for work how the hell do i get a job if i have no one to watch him ever for the interview to start working ? The first week or two to pay for start up for childcare up until i can submit my forms to get help to pay is not a problem because my mom and grandma & even my dad will help me if i ask just for that one week or two and i actually found a a couple of trusted daycares i just need to pick up applications but every time i need to interview or to go to a job fair is crazy ?! 😒 then let alone even though i would do it because i know i have to to get this job but not every time i dont trust to just leave just anyone i dont even know my baby in town i dont know anyone anyway to even ask. I mention town cause its CT so you know sometimes you can get a job in a different town. I feel stuck idk someone tell me something im ready to get a therapist cause idk honestly im losing my mind
