Agree with the posts here. Most babies need the comfort of something to suck when upset or tired and a dummy has now proven to be as good as a thumb! Where I come from there has always been an anti-dummy sentiment, with the thumb considered better for babies; however our son always refused his thumb but was quite happy to take the dummy, so was quite glad recently to read a lot of new studies that show dummy and thumb- makes no difference which baby has, sucking on either helps reduce risk of SIDS.

Our son is now 9.5 mnths and still has a dummy....we keep it only for sleeptime however, he doesn't have it at any other time, only to go to sleep. Fortunetly he doesn't wake up when it falls out!

I read that something like 90% of babies will give up the dummy themselves by the time they are 2 yrs old.
