Thanks for the support! We had another bad night Tues (Night 15), up every hour after 11pm and I finally put him in bed with my husband and went and slept on the couch at around 3AM.
The other thing I wanted to offer if that motrin is ibuprofen and has a less well known side effect of excruciating gut pain which can leave LO screaming for hours. May not be the case for your LO, works well for lots of children but for some who do get that side effect, its worse than the teeth 
It might just be worth thinking through the times he's had motrin and how he's reacted to it.
This may be possible...as I switched from Acetaminophen not too long ago because I thought it might not be lasting long enough, or helping enough. Ibuprofen work SO much better for me, but when I read your post I remembered my husband always complains that his stomach is torn up when he takes Ibuprofen!
Yesterday he developed a moist cough and congestion, and was just feeling miserable. We have been giving him Acetaminophen all day and night, which seems to help a little. He was late to his AM nap, and only slept an hour on the bed with me holding him, then completely wouldn't take his evening nap, but fell asleep playing on my at 6pm. I woke him up after 45min so we could get some supper and he ate good. We decided to have him sleep in bed with us since his chest cold was making him so miserable, and he woke at 12, 3, and 6:30 which was rather pleasant after the last couple days, lol. I did give him a bottle each time as I just needed him to sleep for his sake as well as ours, and to push fluids into him too.
I think our plan for now is to just bring him back to co-sleeping and try not doing the bottle when he feels better, at least until after our trip next week. Then when we get back we are going to try clearing out a room and putting his crib and a sleeper couch in there so we can take turns trying to get him settled in the crib again while the other parent (me!) gets a chance to sleep through the night.
I will keep working on his meals too. He does get a lot of protein (egg whites, meat, cheese, greek yogurt) but we do also give him Cheerios and bread etc with his meals, so we can work on making sure he gets the protein first.
Sorry, I've totally run out of time tonight to read your post, and my boy is running a high temp, I must go to him. But I didn't want you to feel alone.
I hope your LO is feeling better too. Thanks ladies for you time and effort to help my family! I am very grateful that you do this!
