Hello I Have Just Given My 1 Year Old Son

Hello I have just given my 1 year old son 5ml of Calpol as he was not settling due to his teething. Only to then find out my husband has also been up with him tonight an hour ago & he also gave him 5ml of calpol. He is settled now but I am worried he has been given double the amount of Calpol advised. He is 10.5kg in weight.
