What is it that makes you feel like you don't know how to be? If you feel like you are doing it wrong, then that Is just a silly idea. There isn't really a specific way to regress, it really comes down to yourself. I know a lot of AB's will feel like they just can't regress very well because they don't exhibit very many babyish behaviors, but it isn't really about that, its about letting yourself take part in whatever babyish things you have always dreamed of. If you have always wanted to wear and use diapers, that is certainly a good starting point. I personally like drinking from a bottle as well, so maybe that is something that you would find fun. Sometimes watching cartoons is a good activity for many. What is it that you imagine would be a good start?
