Q&A: My 9 month old has had a cold for over a month

Dr. Christine Wood, M.D


Q My 9 month-old son has had a cold for over a month, and the doctor has given him several prescriptions, but they just doesn't seem to work. I was wondering if you had any suggestions? We have also tried various over the counter products and they don't work either!

A I am not sure if your doctor has prescribed antibiotics or decongestants. If antibiotics were used, and have not helped, I would consider the possibility of allergies. The most common reason would be the type of formula the baby is on. Some babies can have allergies to the milk-based or the soy formulas. If you want to see if this might be the case, I would try the baby on a hypoallergenic formula, like Alimentum or Nutramigen for a month, and cut out any yogurt or cheese if he is receiving any of this. Most children will outgrow this type of milk allergy later in life.

If decongestants only were used so far, your baby may have rhinitis, which can sometimes occur in babies. This is a bacterial infection of the nose (similar to sinusitis, but babies this age don't have developed sinuses) and a trial on antibiotics may be helpful.
