My one year old is still having 5-7 wet diaper per day but they're not at regular intervals. Sometimes she wakes up dry from a nap and then has a big pee. Her BM's vary. Sometimes as often as 2x a day, sometimes 3x a week.
Wow, teapot! You're a lucky mama. DD is 15 months old and goes through 10 -15/day, and that's with dry nights and naps. (cloth diapers. Is that what you're using? I thing it would be less with disposables.)
