Until what age do you usually put oil to your baby before bath time?

Baby oil provides hydration as well as moisturizes your baby's skin. It also keeps them warm during bath time. It must be used sparingly, however, so as not to clog up pores and to inhibit the natural oils their skin produces. I think it's safe to place oil on your child until they're about 6 or 7 years old. But you can choose to place oil even beyond this age. There's no fixed rule, as far as I know. :)
