I had the same problem with my son! He dearly loved being swaddled and lucky for me he was small so I was able to do it, but there came a point around 5 or 6 months when he started to get too big to swaddle and like you mentioned too strong to stay swaddled. It was a nightmare because he could not sleep without being swaddled. His hands would immediately go to his face and he'd wake up screaming. Right about that time my mom gave me a sleep sack and what I ended up doing was I swaddled him, then put him inside the sleep sack so when he got out of the swaddle he was still inside the more loosely fitting sleep sack. He still woke up but not as frequently as before I used the sleep sack. At this time I also made him take naps using just the sleep sack on him with his arms out. He didn't like it, but he eventually fell asleep and I think that helped him get used to the idea. After about a week, maybe two tops he was sleeping unswaddled. Good luck from a mom who has been there!
