(But...I am ALL for safety requirements, but it seems that these are recalled due to sizing requirements and the relation of sizing to flammability. My small 6-yr-old wears size 10 pajamas because the tight-fitting ones are so so so insanely small that his skinny arm doesn't even fit through to the wrist. So, as always, please just exercise caution and common sense.)
