Query: Diaper dye goes off on my son

i loved huggies since day one that is all ive used. i had and still has great protection given the fact that he urinates alot. however a couple of months ago i noticed they changed the design on the diaper and all of a sudden my 10 month's old son upper thighs started turning blue all the time and it doesnt come off even after a bath!!!! its ridiculous! so i concluded the diaper dye of the design goes on his thighs. so i have unfortunately change the brand for that reason
