Sadie: Giving it up is %100 the person’s decision. After all, if you no longer feel the need to be little or even uncomfortable with the idea of being in little space, why force it?
And I have heard that a lot of players can go through phases; I’ve had many an ABDL friend tell me that they no longer want to be a part of the lifestyle and throw everything that has to do with being little out, only to miss it after a period of time (be it days, weeks, months, years) and regret purging.
In the end, you can only do what feels best for you (as long as it’s not hurting yourself or anyone else).
