I would also suggest finding a quiet, dark place near your house where you can go on a walk with your infant. As I walked around the neighborhood, she went from refershed by the air, to a bit annoyed that she wasn't able to move around much - I'm sure some neighbors heard protest crying - to dazed and then resigned to close the eyes. I got upwards of 10,000 steps every night just walking around with her, and learned a lot about myself from trying to get her to fall asleep -- pre-bedtime quiet activities, orange/dim lighting, 62-68 degrees and keeping a very dark bedroom. Also, having someone nearby can also help, possibly singing quietly or giving a gentle massage, which can lower cortisol levels. Breastfeeding has also helped us a lot, something as a father you can't do, but a warm bottle can help. Bouncing on yoga balls also worked for us (I went to a hotel's gym just for the ball once). It gets much better though, brave it out for the first year if you can! My 13-month old daughter now goes into the bed on her own when she gets tired and sleeps for long stretches on her own.
