It sounds like you really like you daycare provider so before you jump to an irrational decisions please consider all the pro's and con's of her care. Also try to talk to other parents to see if they are having any problems.
I am a preschool teacher and can tell you a few things:
-Biting is normal and it will happen every single place you go unless your child isn't around anyone his own age
-your child will bite and be bitten- it is a fact and anyone who tells you their child has never bitten anyone will probably also tell you their poop smells like roses...
-make sure your daycare is properly staffed and in ratio, because this may help (you can go online but most infant/toddler rooms are 3 or 5 children per adult). But remember, you do not want a provider who is willing to "shadow" a child because then they are neglecting the other children who are not biting thus rewards the poor behavior.
-Check the daycare's biting policies- most daycares have policies that will say whether or not they send kids home when they bite too much.
-Make sure that are providing proper first aid care- washing throughly with soap and water, ice pack, and if the skin in broken he needs antibiotic cream and a band aid. They should also be writing you a report each time it happens, but should never tell you who did it- that is a severe privacy policy violation and would make you wonder...
-Ask what measures they take to reduce biting because it is usually for 1 of 3 reasons
#1 is teething pains so they should be offering bitting rings or cool cloths. Asking parents to provide teething tablets or Tylenol for pain.
#2 is retaliation over toys or materials: kids bite as a way of showing their anger or frustration during toy "fights". This is because they have no other ways of communication and biting is very affective for them. A daycare should have more that than enough of everything so there is less of likelihood of fighting over specific toys.
#3 retaliation, invasion of personal space, etc. this is the hardest to combat because if can happen any time or place. There are a few things to suggest is to make sure there is the appropriate number of staff, all staff are aware of who is going through a biting phase and keeping an eye on them, separating a child who is biting (I mean at a table with puzzles or something- not a time out) during busy times when biting occurs, like before and after meals or outside times. And children should be shown positive guidance like teaching children that biting hurts (showing them the wound after the fact) and new ways to deal with their frustrations. I have seen children who were bad biters begin to ask for a biting ring- they were simply teething or sick.
If you talk to your daycare provider and ask what she is doing and if she has considered these suggestions you can work as a team to make all the children safe from biting. Also ask her to tell you every time your child bites because in order to stop biting in daycare parents need to be aware and involved.
And in all honesty your son would have bitten at some point anyway- some kids are worse than others, but like I said EVERY CHILD BITES. So please don't blame your child's poor behavior on another child- just deal with the problem as a loving and responsibly parent would do.
The last thing I want to say is don't file a complaint that is unfounded; if another child is biting is may be for a variety of reasons that may not even be the child's, parent's or provider's fault.. How awful would you feel if you met the parents of the biter and found out that they and the provider are doing everything in their power to solve this naturally occurring and common issue.
I hope this helps!
