Who can help me with advice on how to create a better resume?

I'm 31 and have several gaps in my employment history. I've taken years off to have children and raise them. I've moved states and most of my employment history is a decade old and I don't remember all of the information and dates needed to list them. I also have a lot of gaps. Since moving here I had 3 jobs, each one was moving up a pay grade so I took the better job. I was put on bed rest with my second child and had to quit a job. Took time off again, about 2-4 years. Since going back to work I've done only one kind of work. I'm looking to move past that and try for something different, but I'm afraid my "employment history" and skills will prevent me from having the "experience" needed for the job. I've done a lot of different work at all types of jobs. I cannot list them all. I'm looking for advice on how to make my seemingly boring resume attract employers. I've only a HS diploma and no achievements that are noteworthy. Any advice, suggestions or constructive criticism is welcome
