Bobo on a 16-month-old baby's finger. The injury is a week old. There is a small blister on the finger, but the skin around it is red and tight. What should I do?

If the redness on the baby's finger does not extend beyond the line drawn with a pen, it is likely a normal part of the healing process. However, if the redness does cross the line, it is best to seek medical advice. Redness and tightness of the skin around a wound can sometimes be a sign of healing or could be caused by moisture from the baby's mouth.
