Weaning after 11 months

We made it! There's about a month's worth of milk in the freezer and my little one is 11 months...and we're ready. I'm down to 3ppd which I did veryyyy slowly - took about a week. I now pump around 8am, 3pm, and 9:30pm, about 10-12 min each session. I'd love advice on how to slow down - I know I should work on shortening the 3pm session until it's gone, but where do I go from there?
