We got a pool for Rosemary. I don't know the dimensions, but it's a larger, rectangular, blow-up one. It's big enough for an adult to wade in. My question is ... how long can I keep the water in before it's gross? I'm not talking dirt, leaves, etc ... but bacteria-wise? I don't really want to treat it with any chemicals or anything.

Next question. Rosemary had a pretty bad cold about 3 weeks ago. She's all better now, seemingly. Except her voice is still different. I've never noticed such an obvious symptom with her and it makes me nervous that it's lasting so long. It's nasally and a little raspy. Would you be concerned?
