Good Morning!
I am so impressed that you are able to juggle a super intense curriculum at school and being a mom. I would be hopped up on coffee all day long.
I have given up even trying to get on the computer when I am home because the 3yo and 2yo are always trying to help.

That is one of the reasons the weekends are harder for me. I can't get to the Dis for support.
I think the garden is a great idea! Your kids will love helping and it is nice knowing exactly what you are eating. We did it last year. I bought this

and it worked great. We grew tomatoes, peppers, and cucumbers. I just stuck it in a sunny part of the yard, filled it with really good soil and once the plants were in they just took off. It was a fun project and we are going to do it again this year.
Have a great day today!
