three. nails on both little toes going - one black, one 'mobile' when touched. Morton's toes, so get more damage than big toes - one second toe swelled up like a cherry tomato, then my four year old stood on and it burst all over the carpet. Whole top and end of toe hanging by a flap of skin, including the toenail. Will Definitely look for a gel protector from Boots. Thank goodness for the RF forum.
