The process of your baby "dropping" or settling deeper into your pelvis in preparation for traveling through the birth canal is called "lightening." With a first pregnancy this may happen days or even weeks prior to birth. However, with later pregnancies, it may not happen until labor begins, or even during labor, (see information below). Because this is not your first baby, I would not worry that the baby is still high. He should drop once true labor begins. Hopefully you can hold labor off for a few more days, or even a week or two; however, as your doctor said, once you reach 36 weeks, you should be all right. Keep us posted!

"Lightening during pregnancy actually refers to the term used to describe the baby engaging in the pelvis before vaginal birth. It is thus named because as the baby moved down from under the rib cage, the mother may feel a sense of relief in that her rib cage expands more easily allowing her to draw deeper breaths and eat without feeling full so quickly . . .
.It should be noted, however, that lightening usually occurs in a first-time pregnancy whereas in subsequent pregnancies, the baby may not drop until labor has officially begun. It can be a gradual process that happens over several days or weeks or it can be an all-or-nothing event." ( http://www.givingbirthnaturally.com/lightening-during-pregnancy.html)
