Awww, thanks!
And it isn't just my own children. Over the past 21 years I have worked in pediatrics and have been able to do that with so many sick little ones because their parents weren't/couldn't be there. All of the babies born with heart defects came to us and we had the honor of caring for them and watching them grow, doing everything the parents would do if they could have been there.
There's not a lot more rewarding to me than to get a big hug from a patient I watched grow up, or from a family member who appreciated the care I gave to their little one.
