First I will say I am not a doctor and my advise is my personal opinion..
Since 2006 I have spend a lot of time on daycare/pacifiers and I believe in happy babies. So if your baby seams to like the pacifier then that is fine.
I am a Mom and entrepreneur that sell personalized pacifiers at www.coolpacifiers.com
You can learn much more about this solution to "pacifier ownership" and daycares at http://www.coolpacifiers.com/faq/
I hope you can learn more from my website.
Thank you and good luck!
