My LO (4mnths) has a cold. Snotty nose, sneezing, mucus in the back of his throat and keeps coughing to bring it up. I've tried the NUK bulb thing, snuggle babe, raising his cot, Olbad oil in humidifier, etc, etc. But nothing is shifting it. This morning he threw up all of his morning bottle and I think it must be him trying to get out mucus stuck on his chest. Any suggestions on how to get rid? I've taken him to doctors but no help. Just suggestion of Calpol?!?
