Dear D.-
Although you don't mention specifically your daughters disabilities, you may check with her teacher and or schoold district office and/or SELPA if she is in special education. They often have resources that are free and have first hand knowledge of your daughters limitations and also her strengths.
Many children, especially girls at that age, are cruel when it comes to children being different. Your teacher may recommend paring her with a regular education student that his particularly kind or caring, willing to over look that initial first look or action. They can start with small activities to allow interaction.
Many children with all types of disabilities seem to "stand out" and have immature behaviors. They will learn to develope to their potential and interact with others. The school and various personnel are there to help and want what you want for her- the very best.
