Seeking Advice on Managing Alters in a Partner System

Does anyone else have experience with being "The Hands"? we've gone through some rough patches and self discovery lately, both the stress and the unpacking of my traumas has unleashed a barrage of dissociative and formally dormant alters. Some of whom are children or infants. In order to communicate with our partner system and attempt to continue being functional some of our more stable alters have been capable of controlling only our hands even when they cant fully front. it's incredibly helpful but can scare unsuspecting new alters.
