Which is of a lesser evil? thumb sucking or sucking on pacificer? my son (3mths old) has a tendency to suck his thumbs.. so whenever he does so, I will let him suck on the pacificer instead..

Thumb sucking are harder to wean off compared to pacifier. Thumb are easier to reach and may lead to thumb issue beside face and teeth issue. You may find at youtube many ways to wean the thumb sucking issue but it's takes a lot of hard work compare to pacifier.
