Now that LO can roll and squirm and what have you, we've been waking up MULTIPLE times at night because she's either rolled into the crib slats or turned around and her head is pushed against them ... I know bumpers are a no go when they're little but at this age is it ok? We have the mesh ones in but it doesn't give any padding to the head bumps and she's strong enough she can move then if she kicks hard enough!
