I agree, Jtooit. That's what we see, as well. The parents who are low SES (and could use any "advantage" thus conferred, theoretically) are the kids going into full-day kindergarten as early as the school will allow... because they are scrambling to cobble together adequate childcare that they can afford. frown

The ones redshirting are MOSTLY doing it because they want their kids to "out-compete" the other children. These are 5 to 7 year old CHILDREN, and they have parents who want them to "crush the competition" somehow... That. is. just. sick.

My children represent what they are trying to make their child.

Yes-- though they don't really understand what it is they are wanting. Not really.
