is he too hot at night? Is the room stuffy?
My babies seems to be fussy like that if they're too warm or stuffy. I've been known to open the windows even if it is freezing outside.
Getting lots of fresh air during the day tends to make them sleep better at night (why I don't know, but it does seem to work).
Do you have a fan or any kind of white noise? Does baby respond to white noise? Have you read Happiest Baby on the Block? That might have some techniques for calming baby.
that sounds so miserable for all of you! Colic cries that I am familiar with are in the evening until 10 or so at night, but then baby usually settles. It seems surprising to me for baby to cry at night like that, unless he just has his days and nights mixed up. In that case I would really try to get him out during the day in the fresh air.
And then at night, keep the lights dim, and the house quiet.
I wonder if there is something else in the environment that is disturbing him... something that isn't there during the day??
I wish I had something better then my ramblings... Hang in there, if it is colic, that typically ends at 3 months... so there isn't too much longer until then, right?
