Ohhh hugs Ryn, sick unsettled babies aren't fun.

A couple of things that work for us when River transforms into Dr. Whinge were and are, carrying him around in a sling, it seems to calm him and I just wander around the house.
Also co-sleeping, and at first I had to let him sleep on top of me, which didn't make for a comfy nights sleep for me, but now if he's unsettled, he'll sleep inbetween me and dh.

Hope you find something that works for you, and hang in there!
