Pregnant at 43 with two older kids already in college..

My SO and I married when I was 21 and he was 22. We have two boys, 20 and and 18, both out for college. Older one is in his third year while younger one is a freshman. We thought we were done with the whole child raising part and were making plans on enjoying each other's company again. Well turns out I am about 10 weeks pregnant, we just found out. This is a complete surprise and we don't know how to feel about this. Firstly, our two kids are adults already and secondly, we are much older now in our 40s. We feel that we are too old to be raising a kid. When this kid turns 18, we will be in our 60s! I feel extremely concerned and not sure what is the right thing to do. Anyone here had a kid in your 40s? Some advice will be greatly appreciated. We also haven't told our boys, pretty sure they will be freaking out... via /r/Parenting https://ift.tt/2D2J4FU
