Thanks everyone!

I used it on my 15 month old at the time only because I didn't have an honey. Seemed to work. 

I would try the humidifier first. Many pediatricians will not recommend administering those types of products for infants because the risk outweighs the benefits. I would either talk to your pediatrician or the pharmacist at whichever store you're at to get a recommendation.

My pediatrician hates it. Do you have a humidifier? It's really hard at this age to deal with coughs. 

I haven't used the infant one but I use the adult one and it works for me. 😊

I use it on my 13 month old and my mil used it on my nephew when he was around 5-6 until now. It helps a little bit. I usually give it to my daughter before bed so she can sleep better.
