Our bumper has dragonflies and flowers on it and Grace has just discovered them and when I go in there in the morning she is always reaching out to them and staring at them.

Cute.
I didn't think of the suffication hazard as them getting behind it, more of them rolling toward it and having their face pressed up against it. She doesn't roll yet...more shift. I'll put her in the crib so she's straight and when she wakes up she's at an angle.
