Transition out of swaddle

First time mama with a 5 month old and I am so over swaddling. He hates being swaddled but it's also the only way we have been getting him to consistently sleep extended periods of time. We have recently tried one arm out and keep getting 30 minute spurts. We have tried the love to dream swaddle at nap time and it's hit or miss. I'm not sure he likes his hands by his face (we usually swaddle with arms down). I am considering the Merlin sleep suit so if anyone has had luck with that I'd love to hear.

Any other tips and tricks would be appreciated. I know it's going to take time but as a first timer I hate to be missing the obvious! Thanks in advance!
