I suggest these seminal authors for that:
Drs Robert Scaer, Stephen Porges, Bessell van Der Kolk, Gabor Mate, Dan Siegel, Peter Levine - several books by each.
For added insights and help on preventing trauma memory encoding, I'd also put in Self-Reg by Dr.Stuart Shanker and Childhood Disrupted, by Donna Jackson Nakazawa.
I humbly add my own, for that same purpose (in-the-moment or soon-thereafter interventions to quickly ground, re-regulate and therefor prevent traumatic memory encoding):
Compassion In Action: Emotional First-Aid for Children, by Deborah Miller PhD and myself, Jondi Whitis, MTOT
