We just ended up co-sleeping - t'was the only way I got some sleep. We're happy with that but obv doesn't work for all.
You could try putting a hot water bottle in the moses basket to warm it. Remove it before putting Artie in!! It just means it's warm for him like you are. You could also sleep one night with one of his sheets around you then pop that in so it smells of you.
Comma wouldn't be put down even for a moment for weeks so co-sleeping was the only way of getting some sleep. But we have a very big bed so it's easy to do. I carried him everywhere (still do) in a sling as he wouldn't go down in a pram. It drove me to the end of distraction but to be fair to him he was just used to being cuddled and warm and didn't understand not being held.
Despite the dire warnings from my mum, and people saying, "he has to learn", he's starting now to go in a bouncy chair for up to 20 minutes and a swing for an hour or so when he's asleep. He sleeps really well at night and he's away from us in our huge bed so doesn't need our warmth or cuddles anymore so I would now use the carrycot only I find it easier to feed him in our bed.
I still carry him in the sling rather than using the pram because I prefer it and find it easier to use. He loves it which is a bonus but will happily go in the pram now, too.
I don't know if that helps but it's just what worked for us. I personally think the only time doing the holding them all the time thing is a problem is if it's a problem for the parents as it can be so tiring. The babies need that reassurance if they're that kind of child and I don't worry about spoiling them - more allowing them a slow transition from womb to the world and they do make it in their own time.
But it doesn't work for everyone. :)
