It is hard to say until you see the teeth, but if you are worried best you go see the doc. As someone mentioned it could be an ear infection....does bubs have a temp? Charlie got his first two teeth at just 6months and was the same, woke several times a night and would not settle, would not eat/drink a thing and he too got a cough & runny nose. I also have a friend who took her bubs to the doc several times as she had a cough that would not go away, she also had several teeth come through at the same time. So it could be teeth....have you tried any teething gel at night? If that settles bubs then you know that's prob what it is.
