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..

pacifier better as the outer shape can reduce the pressure, better for the growth of teeth. also easier to stop, when lo first got blocked nose after 6 month, it's so easy to stop it. but not so simple for thumb sucking.
