To include or not to include in PS/Application... Nursing Home Business work

Heyo,

Sorta complicated question. Here's the deal: My parents run a nursing home consulting business out of my (our) home. They are pharmacists. They have had me doing typed reports for them and dictate notes from them for basically my entire life. It is important, I think, in that it shows that I am immersed in the medical field. I have thus far left it out of my PS and App... should I include it or no? And if I should, how do I go about including it... For amount of hours, do I put ??? ? Thanks.
