Job switch opinions?

Me

I've been off due to covid19 and interested in switching careers. I would have to do one semester of classes then a 6w training course. I know I would take a temporary cut in my income and it would be a huge shift in my schedule but I know (I hope) in the long run both my baby and I would be happier! I would also make more money in the long run and have more time with my baby ❤️ I'm worried because I would have to find a babysitter during the day when he's used to spending all day with me. (I work nights and spend the day taking care of my baby.) Also I'm currently living with my mom so she agreed she can take over bills like she did before I moved in. Has anyone else went through this or have advice?

And here is a picture of my cutie just because:
