So I'm a sahm. I'm thinking about going back to school. My question is when did you mommas go back after your having kids? I'll have 2 at home with no babysitter and my husbands boss doesn't work well with other people's schedules let alone the workers. I'm scared that I would miss so many classes due to her being a bitch. I really want to do something to get me out of the house but be productive for my family beings we can't afford for me to work. Advice? Please!
