Welcome, Better Half!
This surgery absolutely gave me my life back, and I'm sure it will do the same for your husband.
I would add cell phone and charger to the list and eye shades, so he can sleep during the day and have them on at night. That way he won't be bothered when the nurse comes in and flips on the big, bright light in the middle of the night!
Please keep us posted on how he's doing, and don't forget stop back by after he's home to learn lots of ostomy care tips!
Wishing you both all the best,
Cecilia
