Query: rips up almost immediately

I'm not remarkably picky about these things and we were happy to get this changing pad at such a great price with lots of colored liners to choose from. However, it rips up almost immediately. This may not seem like a big deal - it won't bother the baby if you have a liner on it. Then you realize every time the baby wets the mattress it is soaking into the foam core where you cannot clean it! Next thing you know you have a forever pee-soaked foam thing sitting on the dresser. Yuck. I hate to spend more money on a different one, but we're having our second baby and may have to upgrade.
