My one year old has watery eyes and runny nose, should i give him antihistamines?

Seldom needed: Although used for decades these meds have not been shown to shorten an illness & may increase the thickness of secretions making it harder to cough them out.Many kids felt a little more would help them & self medicated & ended up in emergency rooms.The aap & other groups discourage their use under 6. I have mixed feelings. Saline nasal wash is preferable for younger kids.
