How To Approach Age Regression

[NewLittleBoi]

So, I've been on the sidelines of the community for a while now, almost a year or so, and have recently gotten into a relationship within the past months. I don't know how to approach the topic of being a little/agere (I do both at times, though mainly go into little space. Only sometimes agere when highly stressed or triggered).

 

I've started slipping into little space around them, or have started regressing during breakdowns before, and my partner is very kind and doesn't find it strange when I have accidentally gotten into those spaces, but I haven't told them yet.

 

Can anyone help me figure out how to bring this up? I don't want to scare them away or weird them out, despite how close we are
