Hi crossedwires
Glad this is working for you.
Here's our experience: we started sleep training with our DS when he was eight weeks. I had PND and he never slept for more than an hour. I was going completely insane.
The first night, I put him down at 7 after his bath and nice big feed. He woke up at 8.34 (I wrote everything down so I know exactly what happened!) and cried for one minute exactly. Then he went back to sleep. I was stunned.
We woke him at 10.30 for his late feed, he went back to sleep. He woke up again around four and I fed him again, then he woke up for the day at 7am.
The second night, he didn't wake at all. Or the third night. After a few more months, we dropped the late feed and he started sleeping 7 to 7. He has done so ever since.
He is now 15 months and loves his bed so much he actually goes and stands by the stairgate when he's tired and crawls happily up the stairs and into his room at bedtime. He also sleeps happily for two hours or so at lunchtime. He always greets me with a great big smile when I go to wake him. Sometimes he wakes up and I can hear him settling himself and getting comfy again.
I have never left him crying for more than five minutes. I have never put him down when he's been hungry or wet, and I know when he's crying because something is wrong. I know him very well and I am absolutely confident that our training was the right thing to do for us. He is an incredibly happy, confident little boy and I am convinced that is because he gets enough sleep. You know your baby best, you know what is right for him and your family.
(And having lovely evenings with your husband is pretty damn nice too - it's nice to go off duty at 7!)
