Kindercare allowed DS to enroll in a class for 3-4 yr olds when he was 2 yrs. 9 mos. because he was completely toilet trained. When he turned 4 they moved him to the kindergarten class. You may have more luck if you go to the school in person with your DD. Then they will see what she's like. It is very hard to get people to make exceptions when they haven't met your child.
