I 100% agree with @mommy0527 that's what I do with my 6 month old, the doctor said there isn't any other meds for infants and cough except the zarbees (I showed him the bottle at my daughters appointment tuesday)... I also put vicks in her chest and her feet when she wears a sleeper (she tends to sleep better in just a onesie lol)

You Can Go To Walmart And Get Zarbees Naturals Baby Cough Syrup. They Have Some For Cough And Mucus Too. It's Safe For 2 Months And Up. That's What I Gave My Daughter. You Can Also Get Vicks Vapor Rub For Babies. @jaden_mylove

The doctors won't give any meds for a cough until it turns into a ear infection. Most people buy a humidifier.
