Hi, my dd is coming on 22 months. She's had all of her teeth for about a month now. She is still dribbling a lot, which I would have expected to subside now. She has a dummy but with limited usage in the daytime. Her chin is now getting red and a bit sore which its never done before. I'm just wandering why she would still be dribbling. She has a tooth that had an injury about 7 months ago and will fall out and is loose, could this be causing it? Thanks
