I've been trying to teach my older son, that the best way to conquor his problem with his anger is to learn to laugh at himself. That's true with being a single parent. Keep a good sense of humor. When you turn around and find the baby is blue because he has been in the food coloring, take pictures before you start washing him up. That brings up another point, you may not laugh when it happens, but you will be able to one day.
Kids are great.
I agree that there is a special bond between single moms and their children. There are even times when it is hard to tell who is the parent and who is the child. The cool thing is that God is good, and He watches out for fools, drunks, and especially single parents. Hope this helps some.
