I was - not any more
I was a stay at home Mom while my kids were pre-school. They were the best nine years of my life. My hubby was very supportive, telling people when they asked about my job that I was working harder than him. When the youngest went to full-day school, I started working part time, in the school system, so I had the same vacations they had.
Once they were all middle school and older, I got a 'real' job, with a real paycheck and benefits.
It's not for everyone, but staying home with mine was sure the right thing for me. They all credit me with teaching them how to read, as well as other basic academic skills.
Enjoy your time at home, Sockgirl.
