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..

Personally i think both is fine as over time, they will learn to let go. Mine was easy as i just ask him to throw away in the bin as it was spoilt. After dat, i gave him another one to replace but he declined.
