I would be very concerned about the quality of care the children are receiving. If there is no money left for her own needs you can be pretty sure given her behaviour last night that she isn't putting the food and programming for the daycare highest on the list of expenditures. Also emotionally it doesn't sound like her days with the children are in the best frame of mind - especially if she sees them merely as her ticket to another evening binge. I would be walking on the grounds of safety immediately - and as a provider I would say no you are not required to give paid notice of your intent to leave since you have removed your child due to safety concerns.
