It makes me doubly thankful that I have 4 normal, healthy adult children.
There was a time that I didn't think that both of my boys would live to adulthood - they fought all the time. Now they are the best of friends at age 30 and 31
I am glad for you. It must be such a relief when they become healthy, functioning adults. Mine are 18 and 16 and I just want to get to where you are. No major problems (messy rooms and a little mouthy now and again), but I still worry!
