the piece holding the mattress up has a screw on all 4 corners. you will see holes on the 4 corners of the wood inside the crib. you adjust it there @missbets I recommend removing mattress when you do this :)

I'm not sure on that crib, but usually there are brackets that attach in each corner and they can be moved up or down.

@babyaddi,

@wiccanmommy,

how do I adjust it?

Definitely too low.. You want it on the highest setting until baby is more mobile.

I had mine on the highest setting until he learned to sit up then move it down 1 the 1 more when he learned to stand. seemed to work @missbets every mama is different :)
