Where as, Sallymom, I desperately, DESPERATELY wish I had been able to early enter my middle child (we tried and failed)... Having to wait for age appropriate entry was quite disastrous for us, we watched our happy child disappear, skills regress and ultimately were forced to change schools and grade skip (because that WAS allowed). I really don't think anyone early enters or grade skips a child without considering all the angles, it's not something anyone does frivolously, goodness knows there are enough people around to tell you what a terrible and poorly thought out thing you are doing because their child was so much better off for not having been skipped, or they knew this child once who had a terrible outcome that was clearly because they HAD been skipped...
