I am not one to leave negative reviews, however when there is so much blue dye in infant clothes I must.  I purchased these sleepers after purchasing many Ferber jammies in the past. They are actually our favorite light weight ones on the market. I washed them just like normal then took them on vacation with us.  The first pair our little dude wore and they turned his little tummy a slight blue color.  We washed it off and didn't think twice about it until the next day.  We put him in the solid navy jammies and let him play on our hotel bed (white sheets of course). 15 minutes later the bed was BLUE and so was HE!  I should never have to wash blue dye off our infant!!  Wont be wearing these anymore. :(
