What should I do if my child has a habit of sucking their fingers?
Written by: Early Childhood Education Specialist, Teacher Chan-Chen Shu-an According to Dr. David Levy’s research, children who finish a bottle of milk within 10 minutes (possibly because the bottle’s nipple hole is larger) are more likely to exhibit finger-sucking behavior than those who finish the entire bottle in 20 minutes. Dr. Levy also conducted an experiment feeding puppies with a dropper, preventing them from sucking while feeding. The result was that they resorted to sucking their own or other puppies’ skin, some so vigorously that the skin peeled off.
