Hi guys, my 2 month old has a cold,been using calpol nasal drops buy he's been really ill today so I gave him the said dose of 2.5 ml,he was screaming the house down I was rushing to get to him,the poor thing. It only occurred to me an he later that I forgot to shake the bottle!!! He seems fine,feed well n is now habing a nap but it's the 1st time I've used it n it says to shake for at least 10secs,I'm guessing there's a reason for this n I'm now panicking.what should I do?
