I don't live in FL so I don't know what your regulations are... in CA, the provider pretty much sets their own policies around "expelling" kids, however they are also required to report any injuries that break the skin and require a Dr. visit.
Kids bite for all kinds of reasons. Sometimes there is a need to remove that child from care and sometimes it can be extinguished in a short amount of time. Biting is fast and hard to catch sometimes, but having said that I believe that it is the responsibility of the caregiver to prevent biting as much as possible.
Are you asking as a parent or as a care provider?
I am a daycare provider and a mom. I have had biters in my care, my kids have been bitten while in another care situation (before I had my own daycare) and one of my kids was a biter, so I know all sides of this. Some care providers have a no tolerance policy for biting... one bite and the kid is out... I don't, because I understand that biting is not uncommon in group situations with young children, and it is manageable. In most cases the reason for the biting can be determined and then prevention is the key until the biting subsides. So for example, if the child is biting because they are teething, they can be given frozen ways clothes or frozen fruit to help with their teeth and shadowed closely when in a group of other children. Teething goes away and they no longer bite.
In the past I have told a family that if their child bit another child again that I would not be able to keep her in my daycare. The bite was what I considered severe and aggressive. She never bit anyone again while I had her in care.
As a parent it's up to you to determine whether you feel your child is safe in someone else's care. I would not allow a family to dictate how I run my business or provide care for children. My parents are aware of my policies at the onset and a free to ask any questions regarding them. If they are not comfortable with how I handle a situation they are welcome to discuss it with me but I would not expect them to demand that I kick out another family.
It has nothing to do with money... I always love when people say things like that, with the implication that we will put up with anything or subject other people's children to anything just for the money. Childcare is many many more hours than we are paid for, and a good care provider does it because they love kids, they understand kids and they want to be able to provide the best possible care for them. Believe me, it's certainly not for the money. If that's what someone is it it for they need to find another profession.
