sleep issues in 7 week old...help please :-/

MrsJenC

For the past week and a half or so, my ds has been sleeping like this:

"To bed" around 7 or 8 (which is hard to distinguish from napping at this point??). Wakes around 11 or 12 to eat- so a good stretch, and finished a 4.5 oz bottle.  Wakes around 2/2:30, and won't finish a bottle.  Wakes around 3:30 and not really hungry...will maybe eat 1/2 oz.  Wakes every 30/45 minutes the rest of the night. 

I am at my wits end.  I don't know what to do.  He isn't waking because he is hungry, and he won't stay asleep.  We tried a paci, but he wakes up as soon as it comes out of his mouth.  He is swaddled.  I know he is too young to cry it out, but I really have no idea how to make this work. 

Does this sound like his nights/days are confused, or is this just a rough patch?  He naps for no longer than 2 hours at a time during the day. 

Any input would be great...thanks.
