sterilizing bottles

Aggelgie • much luv🌻💕
I'm due in 8 days. I've sterilized my pump parts and packed them for the hospital. but is it too early to sterilize bottles? 
and is the steam sanitize setting on the dishwasher good enough? 
I know the difference between sterilized and sanitized.. but is steam sanitize good enough? or maybe boil them the first them, then sanitize after that? how early is too early? or should I wait til baby's home? I plan on breastfeeding and once we get the hang of that then i'll introduce a bottle. so should I wait til were ready for bottles to do that?
