My daughter did well with the transition except that every morning, she would wake crying with her little leg stuck through the crib slats. I was concerned about her hurting herself or becoming fearful of her crib. This product was an answer to that, and I'm so glad I tried it. It worked like a charm and now that she's several months older, I don't have the slightest worry that it could cause any issues. Just make sure to read the instructions and install as directed for peace of mind. So grateful for this product.
