Listen to the parents. They have a right to make suggestions about the care of their child. Try not to get angry. Try not to blame anyone. Remember that parents have good ideas about their child's care.
Several minds are better than one.
If you make a mistake, say that you are sorry. Do what you can to correct the problem. If a parent asks you to do something that is not right, do not make any promises. You might ask why the parent feels a certain way. Try to talk about it again at a different time.
