Weaning can be tough but you know your family best and I'm sure you are making the best decision, so don't let anyone get you down about the weaning!
When I decided to stop EP-ing (different I know, but I was pumping 8 times a day for 20 minute sessions so I was still producing a ton) I would go as long as I could stand it before pumping again. Then, I would ONLY pump just long enough to take the 'edge' off and stop. At first I could go 8 hours, then 12, then 18, and eventually it got easier and easier.
If you make the decision to be done with nursing, then be done with it. If you want to continue to nurse once a day, then that's fine too. Whatever your choice, just be consistent for the sake of your child. If you are completely done with nursing, then either pump or hand-express to comfort.
