School options

Hello I’m a younger mom of 3 and as my youngest gets ready for kindergarten I was thinking of going into early childhood education. I want to go to my local collage and would love to work at a daycare or school. Is it fund to do a program like this after 3 kids? I’m a sahm now and would love to start working. My husband supports me in anything I choose. And advise? I know I overthink things!
