B.K.
My son had a no drop side crib which converted into a full size bed, that he uses now. I am 5'1 and didn't have any problems with it. The mattress adjusted with the babes ability to sit/stand etc. When the baby can't sit up, you use the highest level. It's very easy to get the baby in and out, and when it's at the lowest level, the baby can already stand so it's not difficult to get him/her in and out.
I am pregnant with my second and after doing a ton of research, I would NOT get a drop side crib. Even if it hasn't been recalled yet, there's still a chance. If you look of the CPSC.gov webiste (Consumer Product Safety Commission) all of the cribs have been recalled for issues related to the drop side.
Congratulations by the way!!
