it is likely that SS and health visitors/ schools/nurseries will be contacted by the way, im in a similar situationoung kids (i was assaulted in front of my 2 young kids) and 3 months on i have been contacted by health visitor and social work within days of each other.
punishment/ sentence is likely to be community service and possibly anger management type thing but that is just a guess- each case is different depends if the accused has criminal past etc etc, i hope this helped !
