The Situation:
DS sleeps really well at night (he generally sleeps 10pm - 6am, waking up twice, but will go straight back to sleep if you put his dummy in). During the day, he will only do 40min sleeps in his cot (but will sleep 2-3 hours if I hold him, or wear him in the sling). So, I figure it's a problem with being able to resettle himself after a sleep cycle (40 mins). I usually put him to sleep by rocking him (until he is settled, or lightly asleep) with a dummy in, then patting him in the cot until he is properly asleep.
I called Tressillian last night & they told me to ditch the dummy, stop patting him to sleep, and make sure that he is awake when I put him in the cot. I don't think that I want to give up the dummy, because it works so well at night time (so quick to resettle DS back to sleep).

So, I've been trying to work out a plan for teaching DS to self-settle a bit during the day. I'm looking for some feedback/suggestions...

The plan:
* Cuddle DS until he's quiet, but get him into the cot before he is asleep (avoiding the temptation to just keep cuddling!! - which seems so easy at the time...!).
* Give DS the dummy & walk outside the room (fortunately my computer is right outside his room ).
* Keep going in & giving pats/putting dummy back in as needed (ie. each time grizzling starts).
* Keep going for 20-30mins, then give up if it doesn't work & just cuddle him to sleep.
