Actually on second thought, like Happy said..you pointing out the data of S12 of 12 nights and 5 nights just sounds really awkward..why do you need to point that out? She knows how many nights you have him, she made the schedule.

Maybe...

"I appreciate you putting together this new schedule for S12. I am more than happy to have S12, you know I love spending time with him, and I understand the challenges for you staying at your aunts house. I do have a couple things coming up in the next 2 Fridays, so would you mind taking care of him for those nights?"

Something along those lines..
