Your maintanance schedule sounds just like mine except I have a 6yr old and a 9 month old.. I recently setup my tank 2 months ago. No way in hell I was gonna do this during the infant stage. I think what you have going for you though is an established tank and schedule so you should be able to pull this off.
My baby proofing consists of a canopy and door locks to the bottom cabinet.. that's it.
