My daughter was like this as well and honestly, we didn't bother. We wore her in a wrap so we could get on with things during the day, or I just enjoyed sitting with her and watching tv with a snack and a drink within reach (a luxury I would die for now that she is a 2 year old! There is no sitting down anymore!). But I do have friends who've found that holding them long enough to go into a deep sleep (usually 20 minutes after they first go to sleep) means they will stay asleep once you put them down. Or to lie them down in a way that doesn't drop them straight backwards, but moves them sideways into a sleeping space. So like instead of bending over and lying them down on their backs, lie down together on a bed and then once asleep, shift laterally onto a co-sleeping cot (or just leave sleeping on the bed if it's safe). The movement backwards and down triggers a reflex to startle - kinda like if you've ever had that feeling you were falling as you started to drift off to sleep and then startled yourself awake. It's like a survival mechanism to wake and call for help if they fall off something.
