Kindergarten teachers?

Hey all, I’ve spent the past few days thinking long and hard about what I want to do and what career path I want to take. For over 6 years I’ve always thought about becoming a social worker or something in regards to young children. I’ve always thought about being a teacher for young children but never put real serious thought into it. I’m 27 years old and have a 2 year old and it’s now something I’m seriously thinking about. Questions for teachers and younger grade teachers. Is it to late to start? I know the pay isn’t very good and I’m not wanting to do it for the pay.. how does being a teacher affect your home life? As in family life? How does pay work during the summers? How many years of schooling would I need to take for this ?
