Advice?

If I put my 2 week old in his snugapuppy swing at night (it has a way to buckle him in AND swaddle with a certain type of swaddles) will this “train” him to only be able to sleep at night if he’s being rocked or I guess swayed back and forth? We had be co-sleeping (I know how people feel about it so no need to say anything about it!!) because that worked for us and we found a very safe way to do so but I’m trying to get him to learn to sleep away from or off of me so my hands can be free while he’s sleeping. We just got a bedside bassinet and we also have a crib but he doesn’t do well in those. Any tips on getting him to sleep in those? What’s your take on him sleeping in a swing all night?
