The lift issue I'll blame it on the typical inconsiderate and selfish M'sian, I once had to wait for a lift for more than 20 minutes at 1U, since every time the lift arrived it's full, and no one bother to give space for me and my baby stroller.
for feeding areas in shopping malls, I always do my homework first before I went to any shopping mall with my baby, find out where's the nearest babies room. You always can ask at the information counter/concierge
In Sunway Pyramid, for old wing there's one in Parkson, babies section, LL2 I think, same floor with Giant. for new wing, there's one in Jusco, babies section also.
Here's another tip for babies room in any shopping mall, there's always one nearby in the Babies section in any departmental store. If you need to use one, just look for nearest Parkson, Jusco, Metro Jaya, Isetan and head for their babies section, you'll always find one there.
