Unsafe Cot Bed advise?

So my daughter is very wriggly in her sleep, and constantly ends up getting her arms/legs trapped in the gaps between the bars of her cotbed. She screams hysterically, and I'm afraid because of how much she moves that she could hurt herself. I've been advised to use bumpers, however a few months ago she had breathable bumpers, and got her face stuck. Luckily I heard a commotion on her monitor, as she was essentially suffocating. Because of this, I definitely do not trust bumpers. Does anybody have an alternative to bumpers, or have an idea of how I can stop her putting her arms/legs through the gaps? Just worried she will hurt herself.
