When did you stop swaddling?

My daughter is just over 3 months and we are still swaddling her in a halo swaddle for all naps and at night. She’s a small baby at 10 pounds. She sleeps amazing right now. Should we preemptively start doing some naps without the swaddle/just the sleep sack? I’m nervous to mess up her sleep, but I don’t want to disrupt her development or anything if 3 months is too old for the swaddle?
