Induced labor?

I'm currently 31w6days with baby #4. I was induced with my other 3 children, but would really like to experience labor on my own with this baby. My doctor says chances are I'll have to be induced wit this one too. There were a little over 3 years between the first 2 and almost 5 years between the next 2 and now there's just over 2 years between this baby and the last. I'm just wondering if because these 2 are closer together maybe I can go into labor on my own...? My almost 2 year old climbs on me constantly and pushes on my belly and elbows me in the belly. I'm hoping this may help?
