My daughter has been sleeping with only one arm swaddled for a little over a week. A couple days ago she rolled over from her tummy to her back & has been doing it since. Well, today she rolled over about 4 times from her back to her tummy. It actually seems like that’s easier for her than rolling the other way. My question is do I need to swaddle her with both arms out now, not swaddle at all & switch to sleep sack, or is it okay to keep swaddling with one arm out? She’s almost 12 weeks btw
