10 wk old wiggling at night, normal?

Maggie
We still swaddle our 10 wk old little girl and she will sleep 6-7 hours per night. But we will place her in the middle of the crib and when she wakes up, she is against the edge of the crib.  Is this normal? I do not want to put anything in the crib.  Her hips are moving more right now and I haven't seen her roll yet.  Suggestions? TIA
