Parenting as a Christian Single Dad

We had a nice surprise recently and grandma and grandfather paid Madalyn and I a visit. It is always nice to see Madalyn interact with them. She does such a good job it makes me wonder whos kid she is. She got a new princess crown and some other play stuff so now I have to call her "princess". Silly little girl.

She is going to be stubborn like her daddy. After last night I realized that I may not be in control and she is testing me. With all the controversy on spanking I was not sure what to do. I don’t want to hurt her but the bible says “…spare the rod, spoil the child.” Actually the bible has a lot to say on the subject "Withhold not correction from a child: for if thou strike him with the rod, he shall not die. Thou shalt beat him with the rod, and...
