Woombie transition?

Has anyone transitioned out of the woombie yet? This has been my life saver for months because my little man's startle reflex was so strong it helped him to sleep all night. Well now he's 20 weeks and I'm thinking it may be time to start weening him out of it but I'm scared because he's been sleeping 10-11 hours a night with no wake ups. I did try one arm on one time but he hates that because he likes to touch his hands together when sleeping. Thinking of stopping cold turkey and praying it will work 😂😬
