It's amazing the change having children brings. I was afraid to have children in "this system" too and waited 7 years after we were married to have our first. I was depressed and knew that I wanted to raise our son with opportunities my husband and I didn't have as born-ins...especially being able to get a degree.
I'm a stay at home Mom too. Send me a PM if you like.
Have fun fundraising and being part of your community. I'm participating in a charity event for the first time as well. It should be fun!
