Swaddle up

Ka

My boy is about to be 8 weeks old and I'm trying to transition him out of being swaddled. He loves to be swaddled and its not going so well. I use the Halo sleepsack/swaddle. I'm considering buying the swaddle up, but can you still use it after theyre 8 weeks old? Does anyone recommend this or something else? Hes only sleeping 2.5 hour stretches and I'm desperate for some sleep!
