my clothes always shrink :(

I know this is a stupid question.I wash all my clothes on the delicate cycle with warm then cold water.Then I put it in the dryer for 70 minutes(heavy dry then normal dry then cool dry) on medium for heat level.Are clothes supposed to shrink the more you wash them?my mom takes her's out of the dryer before they are dry and lets them air dry in her home.See i think this would make the clothes feel hard,and not soft.I would also be worried about the colors fading,doing what she does.Any advice welcomed
