Cough medicine 1-11 with honey

Jordan • Hi Everyone, I am a mom of two wonderful little boys Maximus & Krue. I am married to the love of my life.❤
My son will be 11 months on January 13th. He has a bad cough and I didn't even see that it had honey in it! I know your not supposed to let them have honey until a year. Do you think this will harm him if I give him this before a year?
