My 10-month old sucks his pinky, ring, and middle finger. His knuckles on his ring finger have split in the crease. It looks soooo painful. Mind you, he has eczema. Every chance I get, I try to put on Aquafor or Vaseline but that is the hand he sucks so it doesn't last long. I fear putting on a bandaid because he may get it off and choke on it. Any suggestions?????
