A little tip when washing babys laundry

I learned this when I got around to washing my first's Christmas clothes at 6mths. Use color catchers! She had a lot of red clothes and the dye in them bled and got on the white that was also in the wash. I was devastated! Now I never do a load of my kids clothes with out a color catcher thrown in. Pic of the ones I use below. Also another trick I use to help prevent from forgetting to toss one in is to put one in the empty hamper then when hamper is full I just dump the entire contents into the washer then toss a new color catcher in the empty hamper for the next load.
