WOW...........this sounded like me 8 months ago, now my business is nearly ready to launch. There is a lot of work in it. I would never have guessed how much time daily i need to spend on getting everything organised, and this is just the development phase, how much more work will it be when we actually start lol.
Very worth it in the long run, but its not as simple as saying lets start a home based business etc, because it definitely eats into a lot of your time, and what mothers have that in the first place. i'm lucky that ds is off to prep full time next year, and so only have my dd throughout the day, but working for yourself is about putting yourself out there, out of your comfort zone and time management.
good luck with whatever you decide to do, and jodi gave great advice to!
