Welcome to both of you!
My wife was able to stay at home until our youngest was ready for school. She now looks back on those years (our youngest is in 9th grade) very fondly. Yes, they were tough at times, but she is so thankful we sacrificed to have her home.
And YES, it is ok to want grown up conversation now and then. Not sure if you are on a budget or not, but we recently published an article on saving money on babysitting. I know that was a tough one for us back in the day. You can read the article here:

God bless you in your important task of parenting!
