Its so awful seeing them so upset. I hope your little one is feeling better soon. I was giving my daughter panadol every four hours and hated doing that plus she was still so upset that i decided to try a teething necklace. I was skeptical, but it was the best buy ever!! She has now got two teeth and has been great with her teething since i put the necklace on her.
We have had it on her for about 3 months now, and there have been a couple of times when we have forgotten to pop it back on her after a swim or something, and we have noticed her upset and in pain again, esp at night. Put that back on, and she is great again! I swear by it. Google whiskers on kittens. You can buy them there and there is information there too on how they work (if you are like me you will want some info too) BUt definitely worth the buy!
