i think the problem is that some parents will give their child calpol at the slightest suggestion of a cold (or even just to help them sleep

) and that this sort of overuse
can cause asthma. so the advice, for some time, has been not to overuse it - BUT if your child is very unwell or (particularly) has a fever, calpol should still be given without any worries or hesitation.
becky, i very much doubt that lucy's asthma was caused by you giving her calpol, there are
many other contributing factors; in her circumstances, with UTIs and fevers, you were absolutely right to give calpol to her. this is when this sort of reporting frustrates me - it makes decent parents doubt themselves and makes them feel unnecessarily guilty.
