I love the Nook Pebble mattress but its a bit pricey. I'm wondering about other organic mattresses: If you need to put a plastic waterproof liner on it, doesn't that defeat the purpose of buying organic? Nook looks like the only mattress you lay the baby directly on, but seems like changing that out in the middle of the night after they poop would be annoying. What is the best eco-friendly solution here?
thanks for help!
