This is one of my many needless worries I can let go of! My husband's friend has been a local middle school teacher for ages. I finally asked her what the local school policy on grade-skipping is. She said they test them and if the test says they should be skipped they get skipped, no problem! She has her granddaughter in pre-school so she can skip since she's a late September baby.
