Hi,
If you are happy to keep him swaddled, then go for it.
I personally broke my lo's serious swaddle habit at about 5 mths in preparation for him going to childcare as I felt that it was just one less thing to be worried about him sleeping properly. I started with one arm out, laying him on the loose arm (sleeps on his side in a wedge). Once he was OK with that, I did one arm out, with the loose arm up. That took the most getting used to. Once he was OK with that, it was really quick to do 2 arms out, which was basically no swaddle as he never really had his legs wrapped. Broke the habit within the week with no real disruption to sleeping.
