Developing a routine between mommy and student..

I started up with school again about 2 weeks ago and I still have yet to find some sort of study schedule to fit in with being a mommy at home. I didn't think it would be this difficult. Lately, Porter has 2 moods...he is either VERY mischievous and adventuresome...getting into and terrorizing our ENTIRE home....OR he is needy and clingy and wanting mom LOTS! NEED HELP!!
