krisp- my ds has got a really bad cold and cough atm and i haven't slept for more than 2 hours in a row for three weeks now- so i feel your pain. i guess the only good thing is i don't have to go to work the next day, you poor love.
ds is off solids too and is feeding a lot at night to make up for it.
the only things i can suggest to you are things we have been trying;
vaporiser in his room
fess little noses sucker to unblock the nose
dinetapp (sp?)
other than that i just wanted to say i know what you're going through and i yell at dp every night lately!
