here is what I would do if I were you
I would take the checklists out of your "context" list. Checklists in or themselves are not action steps. An action step might be "look at before I go to work checklist" That's an action step.
With your checklists if I were you then I would put them in your "Tickler File System"
if you have one set up.
For example, on a day you bring your son back to his mom, put the checklist in the folder representing that day. Then on that day you pull out and you will see the checklist in there.
Another thing that you can do, and i think most beneficial is set a reminder on your phone. If you know that you are going to leave to bring your son home at 4pm set an alarm on your phone that will go off at 3:30pm to remind to you look through that specific checklist. Or if you always leave your house at 8:00am for work, then set a reminder at 7:45am to look at your before work checklist.
Let us know how things go for you.
