Judy Hensler is the 1st to come to mind ... she seemed to tower over the others as the show progressed

Another is on Patty Duke her brother started young and short and later grew right past Patty, Patty herself remained less than a tall girl ... kinda amazing that Patty's stand in double remained not tall as well (just a guess)

Both Jerry and Tony grew quickly to Barbara’s height then she was able to wear her heels. Or maybe I have it wrong. She wore heels in the beginning then as they grew she went to flats. Does anyone know what I’m trying to say?

Yep, I get it. And I agree with CC. That Patty Duke kid really shot up. I think he's the only regular still alive from that show. Both Patty and Schallert died in the last few years.

Oh, and I think Jeri Weil's growth spurt got her a pink slip on LITB.

also Whitey seems to have never grown LOL

yep he was always shorter than the rest of his "classmates." As everyone probably knows Stanley Fafara died several years ago (2003). He died on his 54th birthday.

What a sad life he led after Beaver. Was it because of the show?

The article makes it sound like he went thru high school before having problems, although the timeline isn't given until he turned 22.
