My 5 moth old was diagnosed with cf at 5 weeks old. At 2 weeks we went for a check up and I brought it to there attention when she ate she sounds very respy in the back of her throat. They told me probably reflux. So her next appt. The same thing except she isn't spitting up so no med. Then at 5 weeks being diagnosed with cf they put her on zantac.In Jan. had a cold not bad, End of Feb. had RSV hospitalized for 5 days but couldn't believe how well and clear her lungs stayed. A few weeks later the warmer weather was coming allergy season/ stuffy nose, still raspy in the throat uped her dose of zantac. Mean while been giving her breathing treatments. Didn't think much of it her cheeks were really red thought it was from breathing treatments. Last week we went to see the cf doctor like every month and he put her on allergy meds. and said she has asma and put her on steroids again. Well yesturday she woke up late so I fed her first instead of breathing treatment her face swelled up breathing heavy. called and PA said I don't think it is anything to do worry about steroids do funny things but I told her she has been on them before but still said the same. So I gave her her bottle at lunch time and the same thing called her PED. this time changed her form. to soy and giving her the bottle of new formula and was fine. They think that the raspiness in her throat was this all along.Been doing great today.
