I also found Nurofen helped Aidyn when he was teething as Panadol did pretty much nothing (I think because the Ibuprofen in Nurofen targets inflammation a lot better than paracetamol).

Have you tried freezing his dummies, or giving him a cold bottle of water to suck on? i found that would give Aidyn some temporary relief...

We also used the Brauers teething relief too, which also seemed to help.
