hylands mucus and cold relief

Taylor • Mommy of a beautiful 2 year old girl, an angel baby, and waiting on my second daughter. 🥰
Has any one used this natural relief medicine? Have any of you used it on a two month old baby? I saw reviews online where a couple women had, but they didn't say how much they gave their baby. So my question is, if you have used it on a 2 month old how much did you give them? For 6 month - 1 year it calls for 2.5 ML so I was thinking maybe 1.25 ML for my 2 month old. Any insight? My poor baby's cough is horrible and I just want to help her :(
