For the past two days my 6 month old has been in really crappy form. His eyes are red and streaming and he's rubbing them a lot, he's sneezing and his nose is blocked - does it sound like hayfever or just a sniffle to you? I actually suffer from hayfever myself but mine hasn't kicked in yet and I didn't get it til I was about 16-18. Is it possible for babies to get it so young? what kind of things can they take if it is hayfever?
