Is anyone going to stop working?

Victoria • I`m a 34 year old married woman! I`ve been with my hubby for 10 years and we have a beautiful 5 year old little girl and a 2 year old little girl! We’re TTC #3.
I've always planned on being a stay at home mom, but this past year I managed to get a really great paying job and I know they all expect that I'm going to come back after the baby. However, if things work out according to my set financial plans over the next few months, I'm not planning on going back to work. It's going to be a huge change for me. I've worked since I was 12 (babysitting and cleaning years and things) and now I'm almost 30 and I'm not sure how this is going to go! I've never not had a job before, but I literally can't wait for that day when I know my job is now full time mommy. Is anyone else doing this? Going from a full time worker to a stay at home mom? How do you think you'll cope with not bringing in an income?! I'm hoping I can start blogging or maybe vlogging. Or do something from home to feel like I've contributed in someway.
