Hello

This morning I noticed DD's eye's were a bit watery and a little red, I thought it might have been from the aircon in the car. But they still watery and red and a little puffy. What could this be? Surely its too late for hayfever?
Conjunctivitus? she hasnt been around anybody with it, and her eyes arent pusy or sticky.
What do you ladies think? Time for a doctor visit?

Thanks
