Baby clothes don’t typically fade or bleed like our adult clothes. They tend to not have as many added dyes.
Save yourself from sorting clothes and wash them all in one load.
There are many different brands of baby laundry detergent, but I found it best to use fragrance/dye free products like Babyganics.
Honest Company makes a nice laundry detergent as well but they also do tend to add fragrance to a lot of their products. Some babies are more sensitive to that.
