 
Israeli  kids are really exuberant and they move in swarms which can be  completely overwhelming to a couple of sensitive kids from a culture  that values personal space and manners above all. My kids didn't have  a chance. 
My daughter started preschool last Sunday  (Sunday is the first day of the week here) and managed pretty well for a  few hours. The problem is that prek and kindergarten are managed by a  regional council of the Ministry of Education. So you don't actually  pick where the kids go, at least when you move to town this late in the  year. You get placed. And we got placed in the only place with space  which is a kindergarten. Meanwhile my daughter won't be five until  February. So she's the youngest by a lot. The idea is that she'll stay  there next year too (but her friends will go to first grade). It's not  ideal. And I tried to make a stink about it but no one would budge. So  on her first day a gaggle of girls with the best intentions attack her  wanting to do her hair and dress her up and draw pictures for her. All  the while yammering in Hebrew. My poor girl basically curls up  fetal-like in a corner and sucks her thumb. 
That same  Sunday we went to my son's elementary school to register him. He would  only start the next day. While there he starts to complain of a stomach  ache which I chalk up to nerves. When we get home he crawls onto the  futon (our only piece of furniture currently) and stays there moaning  for several hours. Then I discover he has a fever. And then he proceeds  to throw up for the next four hours. 
May be more than nerves. He doesn't make it to school on Monday.
Meanwhile,  our girl goes back to preschool on Monday and makes it through another  day with the help of some puppets - Shmuli the hedgehog and Morris the  Fox. Trooper.
On Tuesday my son is finally ready for  school. He doesn't have his books yet but he does have his uniform. He  wears his red hoody sweatshirt with the school logo and meets his  teacher, the one we'd heard good things about and were hoping for, in  the front office. 
Score. Turns out all the kids are supposed to  wear green, yellow or red (was it Rasta Day?)* so he would fit in great.  He gives me a kiss and walks to class with his teacher. I pick him up a  few hours later and he looks worn out and like he is about to burst  into tears. They had swarmed him apparently and pulled him in a million  directions and wanted to show him their soccer trading cards and invite  him to a birthday party after school and be best friends. And all he  wanted was for everyone to stop talking. Which he made clear at some  point when he couldn't take it anymore. Poor kid. He was hungry too and  thought he missed lunch somehow. 
There is no lunch at school. It ends at 1:30 and the kids eat lunch at home or aftercare. Only snack at school. Aha. He also can't follow along in class because he doesn't have his books yet. 
Mr.  Rosen runs out to buy his books later that day and comes home $150  poorer with sixty pound of books. That's when Mr. Rosen and I hit a low.  
Why did we take our son out of his amazing school in California so  he could sit in class and do workbooks all day long? And this was  supposed to be one of the country's better schools. 
The next morning he cries that he doesn't want to go to school. He hates school. 
Hates school?  I had never heard him say such a thing. He once told me he wished he  could sleep at school because he loved it so much. My heart breaks for  him. I pull out whatever anecdotes I can think of. I remind him that  his friends Ido and Leonard and Itzel all spoke other languages at home  and had to work extra hard in the beginning of kindergarten to catch up  and now in first grade they are all speaking and reading and writing  beautifully in English. 
It takes time. He humors me and agrees to  go to school. We don't realize it is his teacher's free day (or that  there is even such a thing as a free day) and he has a bunch of other  teachers for PE, music, road safety (this is a big focus in school  apparently - probably because of the way people drive here). He has no  idea what is going on and we are equally in the dark. 
His  sister, on the other hand, appears to be doing well and is making  friends. We are fooled into thinking that she is fully acclimated. 
On  Thursday I pick up my son after school and he has another fever and a  rash on his face and it is clear that he is not going to school on  Friday. He's a mess. I'm a mess too. I just didn't think it would be  this hard and I have to remind myself that it's only the first week and  he's only seven and he is completely out of sorts. His Savta comes to  visit and sits down with him when he's feeling better to do some of his  workbook exercises to catch up. Turns out he likes working in the  workbooks. He learns four letter in one hour. By the next day he's  reading in Hebrew. A switch has been flipped. 
By  Sunday, he's ready for school and he's feeling himself again. I pick him  up and he tells us about a friend, Roi, who he's been hanging out with  at recess. Progress. His teacher and school counselor let us know that  he is ahead of his classmates in math and following along pretty well in  Hebrew. And that he is a clever and wise little boy. He has endeared  himself to the authority figures, as is his way. This morning he tells  me he loves his school. I feel like I won the lottery.
Meanwhile  in preschool, our little girl is becoming more and more clingy at drop  off. She understands that this is not just a temporary thing and she  wants out. On Wednesday I leave her there sobbing. And I spend the whole  day wondering if I should just keep her home. Or demand she be placed  with kids her age. Or start my own preschool. Of course when I pick her  up she's fine. She even has a new friend who asks for her phone number  to invite her over. Progress.
This has been the hardest  thing so far. Harder than the whole 
health insurance debacle. It's made  us question all of our decisions. Was this move the right thing? Would  they have gotten a better education in the States? It's obviously too  early to tell but we are encouraged by their progress and by the  willingness of their teachers to welcome them and ease their transition.  
* I later realized it was national road safety day so the kids dressed in the colors of the stoplight.
