HI CS,
I used to teach second grade and my students LOVED sitting on the rug eating while I read. I think it was more of a comfortable.... a cozy feeling for them. My rug often had crumbs on it, but the rug got vaccuumed every night. I just told the kids that if a cracker or something else touched the floor, they had to throw it away.
Really there are so many germs on the tables, desks, pencils, etc.. that they share. Another child uses my daughter's desk when she is in another room for social studies. (She is using someone else's desk for science.)I wish every teacher would sanitize the desks after each day. Or.. why not let the kids use a anti-bacterial wipe on his/her desk before leaving each day. Anyway... back to the snack/rug situation....
Just remind your child to not put the bottom of his hands down on the rug. (Keep his hands in his lap when he isn't using them.)
If it really bothers you, ask if your child could put a placemat down in front of him on the rug. (Remind your child what side of the placemat should always be facing up.) Maybe the other children would like to do this as well. Placemats can be found for a buck or two.
My twins' teachers are great about washing/sanitizing before snack and right before lunch. I ,too,am worried about germs and getting the flu. You have to get it through your children's heads just how importantly it is to wash effectively before eating, using the bathroom, or cleaning off germs in general. Don't just talk about it- Wash the correct way together so they SEE how it's done. Lather up and wash for 20 sec. or more with warm water. Sing the abc's together or the happy birthday song while washing so your boys know when the song is over, then they may rinse their hands.
I would only call if you are still nervous even after recieving all these posts. But, if you do... calmly state your concerns to the teacher. And... ask if your child could use a placemat.
Take care,
J.
