LOST! White (greyish) rabbit beanie with blue on ears, feet in Rathfarnham or Rathmines area

my son 5 and a half has had Rupert since he was born and is completely devastated! He was lost last week either in the Rathfarnham or Rathmines area please if he is found contact me Asap. He is an off white colour, blue in ears and feet. He is a beanie however all the beads have moved over to one foot from washing! Also as baby he used to chew on his feet and as a result he has stitches on his foot also. Please help us
