Dishwashing Plastic???? Bottle Washing...

Hello all... I have been hand washing bottles and sippy cups forever... I have just started using the dishwasher on sippy cups.. because of all of the plastic scares I was affraid. I did read that color plastic is okay so I then started putting those in the dishwasher... but, with a 21 month old and a 4 month old I feel like I am washing bottles all day everyday... I did buy the born free bottles that are suppose to be made of the safe plastics... are any of you using them and putting them into the dishwasher.. I mean I steralize them in...
