My three and a half month old has recently taken to using the dummy to get to sleep however I think it is responsible for him now waking between feeds during the night. We took it away two days ago and he can go to sleep (in time) but he seems to really need the oral fixation. Will he get used to having the dummy and start sleeping to feeds again or are we right to take it away? If we are not going to give it to him what else can we use to help his oral fixation?
