baby girl is a little over 3 weeks and she has been wiggling to the side of the cradle that she sleeps in and pressing her face against the bars and hanging her arms out. sometimes she even sucks on the bars. is there anything I can do to keep her away from the sides that is safe for a newborn? I've tried putting receiving blankets rolled up on the sides of her but she wiggles right over them and I've tried swaddling her and she manages to free her arms and wiggle to the side again. I need advice on how to keep her away from the sides she's already hit her forehead once that was hard enough to leave a mark and she cried when she did it.
