Baby TIPsters
Baby TIPsters do exist.
It is uncommon, but when a genius kid skips several grades (as is common with geniuses) and then attend TiP, this genius kid is known as a Baby TIPster. The only three recorded baby TiPsters were this girl from East Term I 2009, this one Indian kid and adorable Little Richard from West Term II 2010, all twelve years old.
There was also a baby TIPster at the Duke Institute in 2010, named Pryce. Pryce was small and huggable. Everyone loved Pryce.
Though never explicitly referred to as a Baby TIPster, John Francis is thought to have celebrated his 12th birthday shortly before coming to Duke East for Term 1 2011. (According to Facebook, his birthday is October 29--doesn't say the year. But that means it wasn't shortly before TiP.)
