I remember when I had my little girl at the ped's office for a one month check-up. She was hungry and we had been waiting forever. I got her enzymes out, put them into her applesauce, and proceeded to feed them to her before I gave her a bottle. A woman sitting next to me told me (after she had SEEN me put her med's in it) that she just didn't understand why parents try to feed their children whole foods at such early ages. I was livid to say the least. I didn't say anything to her, I just smiled, but when I got home I cried and cried. My husband was mad and told me that I should have told her off or to mind her own business. In that lady's eyes, I was doing my child an injustice by feeding her a food that her body was not ready for. I couldn't fault her for her comment. I would have liked it better if she would have asked why before she judged me, though.
Bill is right. CF is just not prevalent enough for the rest of the world to understand and it is a very complex thing. I don't like it when I explain it and people say "She'll grow out of it and she'll be fine", but that is an opportunity to educate others IF they're receptive. In many cases they are not, so I just (again) smile and go on about my business. I have received encouraging words, also, but they're hard to come by since negative words seem to stick longer and with more intensity than positive words do. My favorite is "Look at how beautiful she is and how vibrant her personality! That kid has the best of the best going for her and nothing will hold her down". When I get wrapped up in the fact that she has CF, kind words about her and her awesomeness brings me out of it. She has CF, but she's NOT CF.
My thing is ASK before you judge and please listen before you spout off "She'll grow out of it".
