Hi
I would like to refer to a blog entry I wrote called "whose schedule are we on anyway?" In it, I address the issue of induction.
How far past the mother’s due date is allowed before induction? Six Care Practices that Support Normal Birth that labor begins on its own. There are, of course, medical exceptions to this rule - which does not include, by the way, an estimation of a large baby, unless the mother has gestational diabetes. Generally, it is believed that labor should not be started artificially.
Researchers now believe that when a baby is ready for life outside his mother’s uterus, his body releases a tiny amount of a substance, which signals the mother’s hormones, which begins labor.

Personally, I really do believe unless there is a medical issue that put mom and/or baby at harm, you should not induce. Size assumption is not a reason to induce. Please read:

Good luck and follow your instincts.
