I got into a discussion with a friend tonight and we reached a point where we were discussing the use of diapers vs pull ups and the age of our little sides. It got us to wondering is it common to have an age range or do many littles have a solid age? I range from around 2.5-4yrs because I prefer both diapers and pull ups and so it varies based on my mood. I wanted to ask what is your age? What factors contributed to your decision? Any other thoughts on the fluidity of age range? Do you think it's common?
