The thread about this is old, so I thought it was fine to start a new one. I have a sneezy three month old. He's been checked already, and he's perfectly healthy, gaining weight and all, but I think it's the carefresh in the kitchen area along with hay dust occasionally since he only sneezes the most when around that. Is there any alternative to what to use there? I thought Clean & Comfort, and I bought a small bag to test for the next cleaning, but should I just use fleece with a pad underneath instead of any bedding in the kitchen? (I have waterproof crib liners under my fleece) Also. I worry about them eating any of the bedding. I haven't seen them do that yet, but they do chew on everything right now.
