My DD (3) has a chesty cough. Her cough syrup was sat next to the Piriton bottle (same colour bottle and both clear medicine) I gave her a 5ml dose of what I thought was cough syrup and then a moment later realised I had picked up the piriton! The recommended dose of piriton for her age is 2.5ml! She had just had some calpol and her antibiotic too. I am so worried and upset. DH says she'll be fine but I'm wondering whether to ring 111... She is asleep now but stirs if I rub her back. Feel so guilty!
