In brief: Generally 6 weeks
In general this takes about 6 weeks if you are nursing or not, it probably goes a little faster if you are nursing since you release more oxytocin to make the uterus contract.

In brief: Usually by 4 weeks
The uterus does naturally return to normal size by 6 weeks post-partum, but breast-feeding releases a chemical in the brain called oxytocin, which helps to contract the milk ducts in the breast to assist in nursing.
This oxytocin, as a side-effect, also can cause "after-birth pains" which helps the uterus to contract and shrink back to normal size.
