We had 2 UCS and a few small/narrow waterproof toppers. The UCS's honestly got more use when my kids were PT'ing at night than as babies. I just never needed top to bottom waterproof coverage on their crib mattresses. I had a waterproof mattress pad under the sheet and if a kid went through a real drooling stage then the narrow topper. The UCS was great on the twin mattress turned sideways when my DDs were PT'ing.
