anyone give cough/stuffy nose meds at 6ish months for bad cold?

Unknown

LO is approaching that 6 month mark and it appears he is coming down with another cold.  The first one he got was 4 months and we couldnt give him anything medicine wise, we just did the basics (suck the nose, saline, humidifier, incline head, etc).

He was sooo miserable and unable to breathe and sleep and if this cold gets as bad, I imagine it will happen again.  Just wondering if anyone gave a little over the counter cold medicine at 6 months since I hear at that age it is safe to give it to them.  Looks like LO is going to have a nasty cough with this one as well so I am wondering if he can have infant cough meds over the counter as well.
