Would it be selfish of me to miss my son's first year of baseball to finish my degree?

I am in a degree completion program that meets on Saturday mornings for class. My two sons have both started baseball this year, and their games will be during my class time on Saturday mornings. I feel torn because I feel selfish and neglectful to them if I fore-go their first year of games to finish my degree. But it will take me about a year longer to complete my degree if I switch to a program that is not accelerated. Help! I am too torn to make a decision as they are both extremely important to me.
