Be sure to clean your air conditioner vents very often. Curtains can also get very dusty... we were told to avoid carpeting completely. I wouldn't clean our bathroom daily, but it is definitely clean. Another thing-- shower curtains are breeding grounds for bacteria and mold, replace them once a month or so, or clean them very often. I don't think plants are a problem (except if a CFer also has allergies of some sort), but rotting plants are because of pseudomonas (not that someone would keep them around). The same sort of goes for rotting food-- obviously it isn't good for CFers, but why would someone have rotting food anyway (except for those leftovers that somehow get lost in your fridge <img src="i/expressions/face-icon-small-smile.gif" border="0">).I think asking everyone to wash their hands is a bit excessive if they are just entering your home; if they are going to be handling your baby and he/she is very young, it may not be a bad idea. Though I don't think that's been a requirement in order to interact with me since I was about 18 months old. I have allergen covers for my bedding, but that's only because I have dust mite allergies, not just because of CF, and haven't had trouble with them- but haven't been super impressed either. I wouldn't go for those unless it is proven that your child has allergies (to dust mites especially) since they can be expensive.Last thing- I know I'm reiterating what someone else said, but keep the nebulizer equipment very clean. Soaking the 'cups' in vinegar is a good idea- we don't use any intense cleaning products since you are inhaling the vapors from the cup... Lysol residue isn't good to inhale. Another thing is to check the filters on your nebulizer pump often. They can easily be forgotten, but it's important their clean. Keep clean, but don't obsess over it. <img src="i/expressions/face-icon-small-smile.gif" border="0">
