I found nurofen and some bongela worked better for us than panadol on the little ones.
And lots of cuddles.

During the day there are so many activities going on they can get distracted.
At night, they are in slinet rooms, no lights and nothing to do than think about how much their mouths hurt.

Give him some cuddles. It wont scar him for life to sleep with you for an hour or two until the pain relief kicks in and he settles .
