We too had to come to this conclusion and when it was our turn it felt very odd - as you say, satisfying but definitely different - empty but full at the same time and you still have alot of the parenting ahead (at least 15 years or more of children in the house and years of them away from the house bringing them grandchildren for visits) so you won't be bored for some time to come. Like with most things time will make this decision feel normal and eventually you will get to our point of "no way would we want more - it is time for those new doors". I'll remember this as we are going for ds's Learners this week and have bought a used car for him to learn, drive and eventually keep which is making us feel old as dh's Dad did this for all his kids "when he was old". Aint life funny ... do remember though you are not released from this forum or friendships now or even after you relocate, change lifestyles and grow in ways without all the red tape!
Best wishes and celebrate - and do remember, you can always go back and get re-certified if you ever feel too bored!
