Sleep sleep sleep

I was asked what approach we are taking. It's a mixture of things but it looks like this:

1. We watched for natural sleep times (theirs is 5pm) So we bathe, bottle and bed form 5-6pm
2. Put down drowsy but awake (we try to read to them every night but if they are tired we put them down)
3. Compassionate crying - they cried for about three days when we first put them down. We would go in and soothe until they were fast asleep.
4. Nap times in the crib (so they get used to sleeping in their cribs)
5. Focused feed at 10pm (this is as of this week coz we are getting to the last step ...
6. Extinguish sleeping: crying it out basically. These guys wake up coz they want their binky or roll over etc. We leave them to cry for 45 mins and then go in, soothe them in place (i.e. in the crib) and leave again.
7. Once they sleep from 10pm - 6am, start moving the focus feed back by ten mins a night until you hit 12 hours.

Step 6 starts tonight. I am totally dreading it. It feels like my heart is being ripped out when they scream but from everything I have read (baby books through to medical journals) it is not harmful and it's quick.
Ideally we should have a full night (10-6am) by the end of this week.

Hot damn, that is an exciting idea.
