Thanks everyone! I don't remember this with DD, mind you, her worst sleeping stage was from 8-10months and I think it just overshawdowed everything previously!

Marcellus - we don't co-sleep, but he's in a bassinet right next to us - its not during the night that I struggle, its the next day!
Heva - some nights, when nothing else has worked, we do end up giving him panadol, but I don't like doing this continually. Was thinking about taking a trip to the doc just to make sure no other issues.
Zarava - DD was such a quick teether, she'd be grumpy for a day or two, and then there'd be a new tooth, with its pair arriving a day or two later so this "is it teething, is it not" is driving me crazy!
