First and Foremost, I want to say " Welcome to PreK!"
Secondly, I know that this is an exciting time of year for you and your child. 😆 Your child's first day of school is a very important step in his/her life. Therefore, if you have any questions or concerns, please don't hesitate to contact me at firstname.lastname@example.org. I would love to help you all to the best of my ability!
Last but not least, I know that we are going to have a wonderful year and I look forward to getting to know you and your child.
