Help Identifying a Classic Film Insert - Little Girl in Raincoat Playing in the Rain

[youmeus]

Hi everyone,
I am 51 years old and grew up watching Sesame Street in the Caribbean during the late 70s and early 80s. There is a film insert that has stayed with me for over 40 years, and I am hoping someone here might be able to help me identify it.
Here is what I remember:

• It was a live-action film segment (not Muppets, not animated)
• A little girl, by herself, wearing what I believe was a yellow or red raincoat
• She was outside playing in the rain
• She then came inside and her mother cleaned her up / dried her off
• There was music playing throughout - no narration that I can recall
• It had a very warm, comforting feeling to it

I would have been watching around 1978-1984 (Seasons 10-15 roughly), though the segment itself could have been produced earlier and rerun during those years.
It was one of those simple, beautiful slice-of-life film inserts that Sesame Street used to do so well. It was really meaningful to me as a child and I would love to find it again or at least learn more about it.
Does this ring a bell for anyone? Any help identifying it - episode number, segment title, or even just confirmation that it exists - would be hugely appreciated!
Thanks in advance.
