Sorry. I guess you need to be a medscape member to see it. But if you google ibuprofen and infants and renal toxicity you might find some articles or information. We have always used infant’s advil from the time she was very young. Our bottle is different and actually has information for dosing from small weights and our doctor said it was okay so I did it. Benadryl I’d be cautious about for some reason. Though I’m sure it’s fine because I remember Ann Marie saying that she gave Carter benadryl to try to prevent an immunization reaction and I think he’s also around Trace’s age. I’d probably not use it unless you had too for an allergy reason, not to help them to sleep or for teething. Have you tried Hyland’s teething tablets? They helped Hailey at that age, though they do have some trace lactose in them I believe.
