Our pediatrician thinks our almost 6 month old might be allergic to our two cats. Right now he is on Zyrtec for infants and it has helped immensely with his cold symptoms that he has had for almost three months since getting RSV and bronchiolitis in February. We are planning on having allergy testing performed when we have a consult with a pediatric pulmonologist. We already keep them out of his room by keeping the door closed at all times and we have an air purifier as well. We really don't want to find new homes for our cats (we've had them for 8 years) but I'm not a huge fan of daily medication for our son. Any other tips or suggestions?
