Unlicensed/untrained workers

I recently quit a job at a group home for MR/DD kids(under 18)because the woman who owns the facility wants her niece and daughter who are only 19 themselves to run the house and do g- tube feedings and give mneds. These girls have been raised with an aunt and a sister who has C/P,but have had no training. Was I wrong to refuse to risk my license if something went wrong,while they were doing a tube feeding,etc.
