Thanks EW. I like the advice "follow your gut".
Right now DS6 is w/older kids some are 3 years older. It is a mix of good and bad. In fact at 4:30 going to talk to teacher about teasing. My DS says the kids call him "cry baby" "disgusting (cause he picks his nose" "nosy (he always checks out what work the other kids are doing) oh and "a loser" this one he said he replied "yes, your are right I am a loser". So now we have BIG emotional issues!
