Detergent Anyone?!

When it comes to children's clothing you can never be too careful it seems!!!! I've heard many wash their children's clothing in cold water and hand dry their items or prefer dreft for sensitive skin? Some of my children not only have sensitive skin but also suffer from eczema and for that reason I make my own that i came across on a blog. If I can find the post I will update this post when I have free time. What is your preference for washing clothes, what do you wash them in and why?
