It fits!
I tried some of the other brands or infant finger toothbrushes and when I used them, they fit so tight that I could barely feel my finger.  The Nuk Infant Finger Toothbrush & Massager is more flexible and doesn't cut off my circulation.  I am 6'1&#34; and 195 with decent sized man hands.  I'm also a dentist and I would recommend this product.  I use it for my 15 year old handicapped daughter who has Rett Syndrome.  She accumulates a lot of plaque and staining on the front of her front teeth.  I use a regular toothbrush for her back teeth and the inside of her front teeth.  I would recommend this for use ONLY in the areas where you cannot be bit!
