I would say the moment my first child was born, but that moment kept getting challenged every time I brought another life into the world. So I'd have to say I have had 4 AMAZING moments, with 5 incredible children, that I honestly could never choose between. It never got played out, and never could, should I have had a thousand more. It feels new and exciting every time. Birthing a child is just incredible..even x's two::) That is twinsanely incredible, lol. My life has been pretty hellish other then that. A lot of struggles and hardships, but even if it had been a terrific bed of roses..nothing would have compared!
