Incorporating informal caregiving into new grad resume

Hello all, I am a recent BSN graduate embarking on a second career at age 30. My prior career was business management and was 7 years ago. Since that time, I've worked part time in home care while acting as a an almost-stay-at-home mom and also caring for my severely disabled parent in my home; the last four years I did this while full time in school. The care I provided my father included ostomy cares, PROM, ADL assistance, constant assessment for newly surfaced health issues, and general management of his care; however, this was unpaid care provision without an employer. Had he not lived with me, he would have been in a LTC facility (this is where he was for a brief period before joining my household). I should mention his diagnosis: chronic progressive MS- quadriplegic. So, how can I incorporate this experience into my resume so it doesn't appear I've spent the last five years doing little to nothing in the employment realm? Thanks in advance for any advice!
