First Day of Preschool!

Today, Will starts preschool.  Since we are in town for a quick break & have been paying tuition all semester, we thought we would let him go to preschool.
I've never put him in mother's day out or any form of school.
I am a nervous wreck.
I worry about what kids may say or what the teacher might not catch.
I worry about big kids noticing his differences and him not being able to respond appropriately on their level.
I worry about the songs involving "10  fingers" and how normally I make up alternative motions for him to do & what if he doesn't think to make up alternative motions himself and just sits there for 7 of the fingers during the song?
I'm going with him in the morning to educate the class on differences.  I plan on teaching him the vocabulary we use and teaching them what is appropriate (playing with him, holding his hands, sharing with him) & what is not appropriate (grabbing & examining without his permission.)  I want them to know that God made him and he is wonderfully made just as he is.  I want them to know he can do anything they can.  I want them to feel free to ask questions of me - I would rather them hear accurate information from me than go home to their moms who have no idea what they are talking about and may not be able to answer all their questions.  Children are naturally curious and I want them to know it is not a secret that Will has differences.  They are free to ask us about them.  (And I usually find that once kids get their curiosity satisfied, they move on and see Will for who he is rather than focusing on differences.)

I worry about his personality changing.  He's so gregarious.  But, recently, we've noticed that kids staring excessively or mocking him really bothers him. We've had two instances recently when he has just asked to go home - as if he is giving up because he gets tired of some rude little monster child staring at him and mocking him.
I pray for his friends - for new friends to come along side him and protect him and stand up for him.
I pray he can learn to stand up for himself appropriately.  I struggle with how to teach him (ie:  it's rude to stare but sometimes we stare back at people.  Does that make me a hypocrite?)
I pray he doesn't have to learn how to stand up for himself yet.

We went to the preschool today to see the classroom and visit with the director again.  I was so proud of Will as he was now able to turn the faucets to wash his hands all by himself.  When we visited last spring, he wasn't able to reach them.

I practiced tonight with him.  I wanted him to be aware of what mommy was going to talk to his new friends about.  He had a couple of ideas himself.  He wants me to be sure to tell them how fast he runs with his prosthetics on.  I was nervous even going over it with him - afraid he would think for even a second that I saw his differences instead of him.
And when we prayed tonight, he said, "Thank you, God, for my mommy."
3 years and 2 months old and I fall more in love every day.

I have dreaded this day since he was diagnosed in the womb.  I have researched endlessly best methods for teaching classmates about limb differences.  I've talked to a child psychologist at Scottish Rite.  I've talked to other moms further in the journey than I am.  I've read books.
I don't know if my heart can take the fear of sending him to school without me.
Please pray for my heart.  Please pray I can exit the building without being escorted out by security or requiring the use of xanex or valium or alcohol at 9am. :)
