One thing I've realized over the last few months is that I really, really like being a work-at-home mom and can't really see myself being "just" a stay-at-home mom. No one knows better than me that being a SAHM is truly hard work, but maintaining a freelance career as well undoubtedly makes me a better mom. For one thing, it keeps my brain from turning to complete mush. It also helps me stay motivated and organized. There's not much I would change about my current situation. (Of course, I say this at the end of a week where I felt really great about my parenting and the work I was churning out...not always the case.)
Without a doubt, I would tell anyone in a SAHM situation to find some sort of part-time gig or side hustle. For many moms, this would be starting their own business, since those tend to be the most flexible. And if that's the path they were interested in exploring, I would hand them The Miracle Entrepreneur by Ramona L. Clay.
The Miracle Entrepreneur is divided into 7 sections: Setting Your Target Goals, Creative Thinking, Introduction To Entrepreneurship, The Business Plan, Financial Management, Record Keeping and Business Resources. Clay provides helpful worksheets and a ton of great business resources.
The most helpful section in the book, I think, is the list of 20+ businesses you start with $100 (or much less, in some cases). The examples she gives are all great ideas for a mom looking to start a side hustle with not a lot of capital.
