Sounds like teething to me, Caden did the same thing when he was cutting his bottom teeth.
We use nurofen for kids with Caden now when he is teething and its great! as he has one dose of 5ml when he goes to bed(only when he is cutting a tooth or he is sick) and it lasts 8 hours and he will usually sleep through

So you dont need to keep giving it to them like with pamol.
And as Jaycee said, Nurofen is also good as if needed you can stagger it with pamol, so like a dose of nurofen and then a little while later a dose of pamol, and you dont need to give them the nurofen again, as it lasts the 8 hours.
