Ideas for other systems:
Make a little bag for littles to have in case they front while at school/work. This can include comfort items, polly pockets, fidgets, a note, etc.
Not my original idea and I can't find who created it, but make a note for new alters/ alters coming out of dormancy or fronting for the first time.
Pack bland snacks or fruit for alters not comfortable eating meat or doesn't eat a lot while fronting.
Make a playlist for asl words on youtube for alters who can't/don't speak.
Make a list of people who alters can go to of they feel lost, unsafe, anxious, etc.
Get an app where you can track who is fronting when or you can make notes for each other like discord or SimplyPlural or just a google doc. (Not sponsored, just what our system likes.)
Make a multiple accounts for things. If your parents/caregivers/gaurdians aren't aware your a system, just make a second one as a spare/backup account.
Y'all got this and you are doing beautifully
