Importance of exercise b/f breakfast

Hi all,

I have two small children that need most of my attention in the morning. it is difficult to get my breakfast in before 30 min passes, there is no way I could get a workout plus breakfast in before the 30 min mark. How important is it that I do these exercises b/f breakfast? Also, for those of you with small children that need your attention in the morning...how do you get this done?

thanks
