Not read all of these in full, but one thing that we believe is really important, and hard to see for the first, leaving the baby.
he/she cries just because they want attention, or don't want to sleep? Don't continue to pick them up. Same with routine. Keep them in a routine. Bed time is bed time. Their bed is their bed. We have friends with bleeding 7yr old kids who won't go to their own bed, and have to sleep with their parents!? They kick off if you put them in their bed, and they don't just put their foot down. This is important from an early age and it's hard to do, especially as your first as you'll feel the need to keep picking them up if they're not settled.
Also, get them used to noise, and sleeping anywhere. If you are too precious with noise, again, they'll be very sensitive to it and wake a lot.
Really helps as they grow up. We have had parties in our place and the kids were upstairs asleep, didn't hear a thing and this was loud.
You'll often think you're not doing the right thing. Sometimes you have to put up with the wailing, stick with it and you'll get through it. Just stick to your guns. It's so important in the long run and your sanity in life.
