My 5 yr old has had pink eye 4x's since nov. She has seen her ped. Eye dr n has had antibiotics n eye drops. Why does she keep getting it? What do I do?

Need further workup. Pink eye is not always caused by infection so antibiotics are not the only treatment. If your child also complains of eye pain, headaches, blurred vision or excessive tears, a more thorough evaluation by a good pediatric ophthalmogist is necessary.
Need details. My question to you is - is your child special needs? Does your son have blocked tear ducts? If so, this is normal. You can send me a message, if you like. Colds is very common and a lot of times, pink eye are caused by allergies. Give histamines. Nose spray if needed to control allergies. Saline nose wash to get rid of allergens.
