Newborn Squirming While Asleep

Sierra

My little girl is three weeks old, and I’ve noticed that she’s started to squirm and make little sounds when she’s sleeping lately. We hadn’t noticed it before, and it seems to be more frequent when she’s sleeping on her back. We figured it might be colic or just gas, but she doesn’t seem to be in any pain or discomfort. Is this normal? I’m a new mama and don’t wanna jump to conclusions!
