My children's show line-up (my Mr. Rogers/Sesame Street if you will) was

Howdy Doody
Captain Kangaroo (the original Clarabell from Howdy Doody)
Ding Dong School
Shari Lewis (a local girl - her dad used to perform magic in my synagogue)
Wonderama - the Sonny Fox years
Sandy Becker
Kookla Fran and Ollie (Remember Danny O'Day and Farfel? N-E-S-T-L-E-S Nestles means the very best Chawwwwwwwwclet (klunk)!)
Terrytoon Circus (Claude Kirshner and Clownie)

The shows that you mention Jeff (HR Puffenstuff and other Sid and Marty Kroft shows) came a bit later ... more my brother and sisters shows than mine.
