Hi B.,
First of all, a big hug to you. 7 weeks is a tough time, I remember with my three kids we didn't really get into a routine and back to "normal" (although it was a new normal) for 3-4 months. Hang in there, you are doing a good job.
About the sleep - 7 weeks is very young to be "independent." He still is totally dependent on you for everything. I've heard that the first three months should be considered the "4th trimester" of pregnancy. I have two suggestions.
First, there is a doctor who talks about the 5 S's: Swaddle, Side lying, Suck, Sway, and Shhh. These 5 things together can calm almost any crying newborn, it's like an off switch. To do it, first SWADDLE your baby in a blanket so he feels secure. Hold him SIDE LYING in your hands/forearms with his head away from you and his feet toward your belly. Rest your hands on your knees/lap if this is more comfortable (do this sitting down). Give him something to SUCK, either a paci or your finger. Gently SWAY (**NOT SHAKE**) him back and forth by moving your arms in a gentle rocking motion. Finally, SHHH him loudly right in his ear. These 5 things together combine reminding him of being in the womb with the sucking reflex which is calming.
Finally, I'd encourage you to try out some baby wraps, slings, and carriers. My first two were 18 months apart and the Moby Wrap saved my sanity. I could put my newborn in it, he felt safe and secure and would go to sleep, and then I had both hands free to interact with my toddler. I run a store out of my house called Babies Bottoms and More (www.babiesbottomsandmore.com) and we sell Moby Wraps, Baby K'tan, Beco, and other slings and carriers. If you come to the store with your baby I can help you try on different carriers to find the one that will be perfect for you. We're open Saturdays from 1-4 and during the week by appointment (b/c I'm also a stay at home mom). Email me at ____@____.com or give me a call at ###-###-#### if you want to talk more or set up a time to come by. I love helping new moms have a more enjoyable time with their babies, and the wrap carriers are really a lifesaver.
