1) It is RIDICULOUS... to have a rule that a child can only wipe their nose once... and then the rest of the day the child has to, use their clothing to wipe their nose.
At my kids school... and in Kinder, they have Kleenex boxes, on EACH desk cluster, for the kids to use, WHENEVER they need to.
2) Yes, kids get sick a lot initially. But it takes a few days, to get sick. Meaning, your child could have gotten a bug even before the 2 days she's been in school, and then it is showing symptoms, NOW.
3) Per the Teachers at my kids' school... a parent has the amount of contact with their child's Teacher, as much as they make themselves available. Meaning, some Moms are on campus daily and walking their kids to the classroom and seeing/chatting with the teacher. Some Moms, are never on campus or cannot be, therefore, they do not have any contact with their child's Teacher. BUT, per my kids' school... a Parent CAN e-mail a Teacher. And the Teachers TELL the parents this. And the Teachers, DO REPLY back to the parents.
4) Both my kids, started Kindergarten at 4 years old, and then turned 5. They are both late born. They were fine. But yes, at times, they got sick/had colds. I kept them home and per the Pediatrician's recommendation.
Right now, my son, who is now in 1st grade, he has been home... sick... ALL week. He has also fevers and other symptoms. PER our Pediatrician, I have kept him home all this week. BUT... I DO have contact with his Teacher... in person and on the phone and via e-mail. I as a parent, am available to the Teacher, and she is also available to me, as a Parent. I have, DAILY, gotten my son's homework each day, then taken it back to the Teacher the next day. Daily. The Teacher, appreciates this that I do this and take the time to do so, as I do appreciate her efforts... that she MAKES sure, that my son's homework is ready for me to pick up, DAILY.
It is a reciprocal... attentiveness. Per the situation.
At my kids' school, this is how it is.
You need to get to know, your child's Teacher. As well. So that, yes, you can "trust" your child's Teacher... and understand their classrooms routines/rules/habits etc. And so that, you feel comfortable.... in asking the Teacher anything, or questioning things. As is typical that parents have questions.
None of my kids' Teachers, have ever been, less than professional or caring, in this. Toward their students or toward the parent.
Again, the amount of contact you have with your child's Teacher... also depends on, how the parent, initiates contact WITH the teacher as well. Or if the parent, makes contact with the Teacher. Or not.
I have always had, good contact with all of my kids' Teachers. And they know, they likewise, can contact me ANY time. In person, on the phone, or via e-mail. I nurture, a 'relationship' with them. They appreciate it. They tell me that. And it is professional.
