Who was that nurse?

In the scene where Dagwood is in the expectant father's waiting room at the hospital, a nurse walks up to him and congratulates him on the birth of his new daughter. The actress playing this nurse looks and sounds like Sylvia Fields, the lady who played the first Mrs. Wilson, the next door neighbor to the Mitchell family in the Dennis The Menace television show from the 1950's.
Unfortunately I can't confirm this since she is not listed in the credits for this film.

The only Blondie movie I could confirm that Sylvia Fields is credited with appearing in is Blondie For Victory. She appears as one of the Housewives of America who hold a meeting at the Bumstead home.
