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..

I also find pacifier less evil but not necessarily every minute they had to suck on it. I only give my lo the pacifier when I need to calm her down or put her to sleep when she is crying badly. Thumb is always there so I find it harder to get rid of the habit.
