I always gave Medised to ds when he was teething/had a cold, but it was 3 months+ then.
Have the ingredients actually changed? Is there something in there that toddlers and babies shouldn't have? Or have the guidelines changed because of some new research?
I know a lot of parents with dc the same age who blithely still give Medised - they usually lie to the chemist to get it! Calpol just isn't cutting it with dd at the moment - she needs sleep but she's too poorly with a cold and her top teeth coming through.
