Washing Baby Clothes

Hey I have a question - A lot of my son's baby clothes and blankets are that fluffy soft polyester material and it seems when I wash them somehow I'm doing something wrong because they come out feeling stiff and course.
I have to use a laundromat at the moment and what I'm doing is using baby detergent, bleach and fabric softener on a warm wash setting and then putting them in the laundromat dryers at high temp.
Any tips on what I can do to keep the fluffy softness?
