G.K.
I'm 5'3" and using a drop-side as well, and I'm not even considering using anything else. It's an older model; I used it when I was a baby, and it's been used by my sisters as well (I'm 33). I don't even think mine has a model number or even a brand name for that matter. I agree with Crystal T; not every crib will have that problem. Just go with your gut, like a lot of other things when it comes to parenting, and be mindful of safety.
