4-6 if I were more AB, I think this would be right on! ... Well, except I must wear diapers!!
Oddly enough, I think I was about 4-5 with my first positive diper experience and 6 or 7 when I first discovered my love for dips.
At 4-5, I have a VIVID memory, my family spent the night at my parents friend's house, out of state. I got real sick, trowing up and diarrhea in my undies. The lady found me in the bathroom and really helped me, comforted and cleaned me up and then offered me a diaper since my undies were spoiled and in case I got sick again. I was out of it, and she was so kind, I just went with it. I don't think I woke up again. The next morning, I felt a lot better and my pants & undies were still in the wash so a ran around and played all morning in a t-shirt and diaper!
I struggled with bed wetting on and off my whole childhood. I got punished a LOT over it! And dispised diapers when forced! But around 6 or 7 I found an unused diaper by the dumpster of our apartment. I took it home and tried it on, for some reason it was like heaven!
I wonder if, when I consider an little age, I think that? Plus, I guess, with my youngest kid being 4, I actually don't mind the cartoons she likes and the Independence she has while still embracing sippy cups and blanky and lion. That all seems ideal to me!
