i gave my niece motrin and my mom gave me motrin as a young child she will be okay
Motrin contains ibuprofen, which can cause reyes syndrome in infants. My daughters pediatrician told me to use infants tylenol our an off brand containing acetaminophen. I would discontinue the motrin and get some infants acetaminophen.
I meant to add that motrin is safe to use at six months.
