My 18 month old NEVER lets us put teething medication on her but it has always worked so well and helped her a lot. I didn't want to have to hold her down to give it to her so instead I started putting her teething medication on her tooth brush and I would brush her teeth with it and then let her chew on it for awhile. It's helped so so much! I always make sure to wash the tooth brush off obviously and that's not her normal tooth brush that she uses to actually brush her teeth(:
What are you using?
That stuff is so dangerous.
