My daughter is nearly 6 months,has a nasty cold, I ve given her 2.5ml of calpol & 0.3ml of ranitidine for her reflex. Can I also give her some piriton as someone suggested it helps to dry up the snot? She s really struggling to sleep she s so bunged up. I have done all the usual, chest rub, plug in vapouriser, saline nose spray, raised the cot, which just doesn t help.
