I stayed at the same company but went from management to working part-time after my first DD was born. After my second, I stopped working outside the home for a couple of years. From a financial standpoint, it just didn't make sense for us to put two children in childcare. I wasn't sure how I would feel before having kids, but I really wanted to be home with them those first few years.
When youngest was about two, I started doing some freelance and contract work out of my home and the kids went to MDO once a week. Later, I also did sub teaching work for DD's preschool. I got a great part-time job when youngest started kindergarten, and my hours keep increasing but at a pace I'm comfortable with. I enjoy being able to pick my DDs up from school every day, help with homework, take them to after-school activities, etc.
It really worked well for me and my family. We have to sacrifice a lot for me to stay home, but once both my kids were in elementary school, I was really excited about returning to the work force.
