I am about your age with 3 kids the same age as yours. I went part-time last year and plan on ER very soon since I can financially. If your social circle is tied to your work like a lot of people, and you are excited each morning as you set off to the job, then keep working and hire the domestic help you need.
If you are not socially tied to work, dread going in each day, then fire the domestic help and spend the quality time with your 3 kids. With no cleaners, maids, babysitters, etc, you will not get bored with 3 kids! In fact, you will find a lot more challenging opportunities to volunteer as they go in to high school, a lot of neat science and other trips, projects, mentoring, etc., not to mention to help them in home work and the challenging teen years. I don't think you would regret spending these next 7 or so years with the kids, you can always go back to work when the nest is empty.
