My husband and I have been married going on 27 years. We have a 25y.o. son, 23y.o. daughter, and my 32y.o. stepdaughter who we have raised together since she was 4y.o. We found ourselves pregnant again at 40y.o. and I was 41 when I had our daughter, who is now 8y.o. I wouldn't change it for the world. Yes, it seems we will never be married w/o kids as we now have our 7 month old granddaughter who we are raising. There's not much I would change except maybe just to spend more time with my older children when they were little, time passes so fast. So as far as having children at all stages of life, we've been there, done that. There are things I know now that I didn' know then and things I could do easier then than I can now, but there is always something new to learn. It remains an ever evolving cycle of learning, but we love it.
