Pool cover

Just bought a house with an inground pool. Does it need to be covered for the winter? I have an infant and was told that a cover can be as much of a hazard than no cover because of entrapment. I was thinking about getting a large tarp and stringing it tight over the pool. I have seen really really expensive plastic covers that you can stand on, but we're tapped out from buying the house. We will keep our kid away from this area of the house, but....you never know. Any suggestions?
