Hi all - I posted a question on here a while back about my little Lauren and her use of a nebulizer. She has since been diagnosed with asthma and we have our own nebulizer. It's not bad, we are getting used to it and were told we should only need it when she shows signs of getting a cold etc. Well, yesterday she started having trouble with congestion/mucus again and her breathing got difficult. At times she sounded wheezy so we started the neb last night before bed. She woke around 2am and still sounded pretty bad so we used another treatment, and this time it didn't really seem to work. She continued to cough every few minutes until at least 5:30am - I lost track seeing as I had been up since 1am (took some meds of my own for a cold, apparently messed with my precious sleep). She's coughing up clear fleghm (sorry) and spitting it up a bit with bubbles out her mouth. She was like this a few weeks ago but had a clear cold with runny nose. This time it doesn't seem like she has a cold (yet?). For my friends out there with children on a nebulizer - what can cause the breathing difficuties if not a cold? Is it allergies? She's been congested at least a tiny bit since she was born, basically. Could it be the dogs? I love my dogs but I love my kids more... I'm just at a loss. I'm taking her to see the doc again today - I'm wondering if I should push for allergy testing? She's only 4.5 months old - one of the docs in our practice even said previously that most infants don't develop allergies that young. Any advice would be appreciated! Thanks!
