I am by no means professional, so take this with a grain of salt (or three).
You should start with an outline, no matter how skeletal. Decide whether you want to go chronological or by some other order.
I usually move on to basically writing short stories for each chapter, making sure they tie to the next(and in the case of fiction that proper setup and foreshadowing for future events get put in. That doesn't seem as necessary for your work.

I have been wanting to write a book about the funny experiences that I have had while raising my now 6 year old Quadruplets. I love to write but since having the kids have not had much time. I am curious if anyone has any ideas for how to get thoughts organized and on paper to make for a good read! I appreciate any advice! thanks!
