I have actually found the opposite true Nic... Nurofen seems to work much better for Aidyn than panadol does, but maybe each person/case is different.
I have alternated the two (nurofen and panadol) when Aidyn has had ongoing fevers, that way he isnt having too much of the one type of medication, and it pretty much stays on top of the fever.
Soph, 37.4 degrees is only a very low grade fever so I wouldnt be too worried, its only if the medication doesnt bring it down to under 38 then I would be taking her to see a Dr.
Meg - Nurofen for children can be used from 6 months old.

I hope Lucie is feeling much better soon!
