Being a parent is all of the above, and all at different times in their and your life.
It seems that as they are growing, each day can have a little of all that you have listed. Some children are difficult to wake up, you are frightened to let them go off to school, for fear of the unknown. The wonderful report card can be rewarding for you both. This is just one day in the life of a parent, and what one would term a 'normal' day. It gets a bit more difficult when they get older.
The rewards for the parent are everyday in the life of the child, then when they become adults, the rewards are much greater. We are allotted Grand children, that is like the 'Grand Prize' for a job well done!
