Hi
You know at this age, I would aim for AT LEAST one good nap in the crib. Swaddled. Usually the first nap is the most restorative.
My best advice is to tackle one thing at a time hun. I know that swaddle is a pain now that he is becoming mobile. I went through the same thing at that age.. he just didn't like the swaddle anymore or started getting out of it, but he still needed it. I kept it as long as I could. I would tackle one thing at a time- so maybe start but working on a good A time and first nap in the crib, swaddled completely. Once he seems to get a decent nap in the crib swaddled, then you can work on maybe unswaddling during the day. If you really want to ditch the swaddle, I would start in the day first and do the one arm out or leg... etc. Swings are a prop and being rocked to sleep is what he is used to-- so getting him to sleep in the crib for the first time will take a bit of time. But one thing at a time love

....at this age I used and did whatever to get my LO rested. Around 4mths I worked on more "independent" sleep.
Do keep in mind that short naps are super common at this time. As his A time increases and sleep patterns change, they should get longer around 5/6 mth mark

...at this age what I did was try my hardest to just get my baby rested as best as I could. Can you resettle after short naps? So if he wakes/short naps, can you resettle back to sleep? I would try that at least with one nap so you can get one longer nap in his day. When he wakes, go in and rock him, hold him, pat, or whatever you do to try and send him back to sleep
As far as his EASY I don't think you should focus on the clock with feeds... just feed on demand. The goal is just not to feed to sleep, kwim? So long as you continue the Eat Activity Sleep routine. If he's not hungry when he wakes, that's ok. You can feed him a bit later or closer to his next nap so long as he's not being fed to sleep... you know? Feed, then start your little wind down routine, then nap
Here are some examples of routines around this age. Again, no two days are the same. Inconsistency will def happen
chronological EASY samples, 0-3 monthsHope those help just so you have an idea. At this age though, it's just going with the flow and doing whatever to keep our sanity
