TITLE: 16 month old with bad allergies, help?
POST: My 2nd child, a 16month old boy, is apparently dealing with his first bout of allergies due to the unseasonably warm weather.  He really has a great attitude about it, but his eyes are very swollen and the sheer volume of eye-boogers is creepy.

A little cough here and there, but he's eating fine, etc.  He weighs in the area of 27-28 lbs (~2 st), I'm trying to figure out the proper way to handle this; if there's a baby allergy med out there I don't know about and dietary adjustments that could help.  I didn't develop allergies until near 30, and the wife doesn't have 'em, nor does his older sibling.

It's affecting his sleep, and his vision, and I want to make sure I'm doing everything I can.  Thoughts?  Opinions?
TL;DR: 
16 month old has bad allergies.  he's around 28 lbs, or about 2 stone for you limeys.  Got any tips to make his life better?
