Personally, I would establish early in the cover letter that you are looking to make a change, but would not give reasons or details. So something like, "Currently I am a successful full-time Content Expert at a busy firm, and I am pursuing a career shift to a part-time position in [target firm's field]." Then the rest of the letter is all about your experience, how you would add value, etc., with a strong suggestion that they would be getting a lot of bang for their buck in hiring someone of your credentials.
At the interview, I would be frank about seeking fewer hours, but vague about the reasons. So, something like, "Due to family obligations, I need to limit my hours. That's why I was so excited to see your part-time position advertised -- because it would allow me to work part-time while still [insert positive thing about the content of the job]. I am a great fit for this position because [substantive discussion, leaving the hours issue behind]." I don't think there's anything wrong with them knowing the details of why you want to work part-time, but you don't want that to be the focus of the interview. You want to acknowledge that you are making a career change for personal reasons, and then move forward with selling yourself.
Good luck!
+1 I would definitely stress that you like the part-time aspect so they won't think you're taking a lower level position and hoping to move up fast. A lot of people do that (which is understandable) but it can make it hard for places to keep good people in the part time/lower level positions.
