B.C.
I feel ya! I'm not a single mom, but I used to be with my first daughter. With #2, I decided that I wasn't going to leave her even for a bit! She's 2 1/2 now. I did in-home daycare for 2 years and just recently quit to do house cleaning. Aubrey is old enough for her excellent pre-school, so I enrolled her there for 2 days a week while I clean people's houses.
Doing daycare from home was about the most stressful thing I ever did, but it allowed me to stay home, and both my daughter and I really bonded with most of the kids that I took care of. BUT, I don't regrett quitting at all. I knew it wasn't what I wanted to do forever. And Aubrey outgrew it. She was tired of having to share her personal space with other kids, and I don't blame her. Good luck with whatever you choose to do!
