I would keep it to a small paragraph with less than 3 sentences. They don't care about that time in your life.
We had a panel during one of our Psych club meetings in college and I learned so much from these professional people who go through resumes by the dozens daily.
They said, each and every one of them, that they glance over the resume looking for the education and experience for what they are hiring for. They do not look at long paragraphs, they do not look at long job descriptions, etc...those are drawbacks. They discount each activity that has nothing to do with anything that is not directly related to the job being applied for.
They all have engineering degrees that are hard degrees and the fluff stuff gets in the way of their search. If someone has a lot of that stuff on their resumes they toss them without even reading them. It means you like to talk too much about non work related stuff.
They think the only things important is the information directly associated with the job they are applying for.
So I would encourage you to have your resume on your computer along with several cover letters. Each one should be directly written for the specific job you are applying for.
For example. I have basically had 2 careers in my life with some experiences in a couple of different fields, developmental disabilities and child care.
If I am applying for a job with a company that offers services for developmentally disabled persons I focus on those jobs I have had in that field. My cover letter talks about how much I love working in this field. How much I could bring to their company, what I would hope to contribute to their companies bottom line.
I would not discuss anything I have done other that my job achievements and any professional associations. I would not talk about staying home these past few years to raise my grand kids to school age. Unless they were disabled and I was using my skills to care for them.
When listing other jobs I would cut out anything that is not related to the job at hand. Such as writing a curriculum for a 3 year old class. If I am applying for a job in a child care setting that is good information to have under past jobs, if I am applying for a job in developmental disabilities it really has no germane purpose in being listed. I would add more items along the line of developing programs for them that helped them to learn skills needed in daily living. Saying the same thing but with an emphasis that is more for the job I am applying for.
