6mo still swaddled

Yep. What the title says. Ive tried a slow transition, or going cold turkey, ive given it weeks, however he WILL NOT settle without being in his swaddle bag. I always thought 6 months was the maximum, so now I’m feeling mom guilt. He will literally flap all night, wake himself up crying every 20 mins when he does finally settle. The second I give in, and pop his arms in the swaddle, he’s sound asleep. Anyone else in the same situation? Any advice? My other 2 were great with the transition so ive been here before. However this little monster is having none of it!
