Advil concentrated drops.
Used these over Xmas whilst on holiday and brought some back with me.It's an American product but seems to work MUCH better than Neurofen even though it is Ibuprofen based.It is concentrated so only need to give 1.85ml instead of 5ml and is long acting-6-8hrs.
Only available in the US but if anyone is off there you may like to try it.
DD loves it too-makes dosing very easy.
Oh,also comes in very small bottle so great for handbags.
