First Day Of School

My little Lion starts school today. PJ starts Kindergarten tomorrow. The first week is all half days (with Lion going till 12:30 and PJ going till 1:00). It's a "get to know you" kind of a week.
I'm not so worried about PJ. Hes one of those amazing kids who really and truly does bloom where he is planted. He can thrive in any situation.
The Lion however...he was the one that kept me awake last night with worry and anxiety.
If my kids were plants PJ would be a weed, able to take hold and put roots down and find his patch of sunlight wherever. He's smart and he's a mellow little guy who rolls with the punches and goes with the flow.
The Lion....well he's more like a delecate orchid. He needs just enough water, sunlight, vitamins, special soil, the air can't be too hot or too cold, he needs to be given a little more attention and a whole lot more patience than other flowers in his nursery.
Last year, I never knew what kind of day it would be till we dropped off in the classroom. He would be fine and the second we hit the door he became this hysterical creature who did not represent my son.
Sobbing, screaming, lunging for me, howling "Mommy! Mommy! Mommy!"
His teacher last year was a Godsend because she totally "got" him and developed a relationship with him and I knew that when I left weather he was eating playdough or screaming at the top of his lungs, she would care for him and not lose patience with him no matter what.
She took extra time with him and gave him exactly what he needed to thrive.
Starting a new year with a new teacher (Who seems very nice and I've been told is a seasoned vet in the school system) I worry. I worry that his teacher won't have the patience to look after him the way he needs. I worry that she won't want him to be her shadow and she won't love him the way he needs.
School starts in an hour. My stomach is in knots...
