Thanks for sharing this journey too...
I'm not sure if this will help - but we found that it was better for our bub to be a little bit awake (ie. eyes openish) when we moved him from our bed to his basket or from sleeping in someone's arms to his basket - that way he seemed to know where he was and be happy to go back to sleep, whereas if he woke up after he had been moved he'd be quite upset.
Usually just not trying to be really quiet when moving him did the trick, or giving him a bit of a hug first.
