Is it ADVISABLE to take all the dummy's off my lo he's 5 months old now and I want them off before he a year old, but I'm being told otherwise my family and parents that's it's not ADVISABLE, and that the child needs that for comfort. My lo has started using a taggies blanket as comfort now instead of a dummy so I think he's going OK x
