Answer 1

You go by weight that is always the safest bet according to the pediatricians my boys have seen.  They said that age is just to tricky because medication can cause overdose if they weigh to little for the average child that age so to make sure to go by weight whenever possible.  

Answer 2

always go by weight, not by age. if they weight is good, then give that dose.  

Answer 3

Please don't give your baby any new medications unless you check with his pediatrician first. You don't want to take any risks with your baby's health.  

Answer 4

You always go by weight. You should check with your doctor. Their weight changes so fast when they are so young.I haven't given my little one motrin yet. I feel more comfortable with tylenol especially with the damage motrin can do if they don't eat first.
