Hi! I wouldn't worry too much yet...you still have several months to go. I would suggest putting her into a summer school program at one of the pre-schools this summer so she gets used to a classroom, teacher and other kids. She'll probably have so much fun, she'll realize that although being with her sisters is great, it's pretty awesome to be with other friends without her sisters, too. Then you can use the time to tell her, "see, kindergarten will be like this, you get to meet so many new friend, you're just going to love it!" And whenever my pre-schooler (who is also going to start K in the fall) gets clingy when I try to drop her off at school, we play the "push mommy out the door" game. I drop her off, hug and kiss her, then say in a confused voice "what do we do now? don't we push..." then she finishes off with "mommy out the door" and literally pushes me out the door, while I pretend to want to stay. "oh no! I'm being pushed out the door !!" etc. It really seems to work! Also the suggestion about setting up playdates with future classmates is a great idea. Then she would already know some kids in her class. If you can't set up playdates before school starts, then set them up as soon as school starts so you can get to know other parents while your daughter gets to know the children. Contact the school to see if there will be any "socials" before school starts or open houses for the kids to meet the teacher and classmates before school actually starts (a lot of schools do that these days). I think some schools may even let your daughter spend a morning in the classroom this year, just to check it out. Again, contact your school and ask them about this. The most likely scenario will be that she'll be shy and unhappy for the first couple of weeks, then meet a couple of friends, then narrow it down to that one "best" friend and then you're all set. She'll soon be running away from you to get to her classroom even faster. At least that was the case with my 2 older kids who were also very apprehensive about starting school. Good luck!
