Pacifier/soother advice

Hal

My first little would not take a soother as he was sucking his index finger straight out of the womb! My second little guy is 2 months old and is showing more interest in the soother than my first. He is quite happy to take the soother throughout the day and will often use it to fall asleep in the crib. Should I continue to offer it to help him soothe to sleep or avoid this sleep crutch/aid/habit? Advice good or bad is appreciated!
