The last 3 nights ds has screamed a lot before bed which we put down to teething as he'd just cut two teeth and we gave him calpol and he slept a lot almost completely through the night. Last night, no screaming so no calpol and he's been up every two hours. Do you think the calpol gave him pain relief and let him sleep? Should I give it even if no screaming so we can all get some sleep. Thanks
