Im sorry to hear that, it's horrible when they are really upset and chesty - plus it sounds awful.
My DD was the same from birth - once when she was really bad I had her in the bathroom with the taps on hot in the sink and the bath, to try and get some steam for her. It helped a little on that occasion.
What she normally does is hack away for ages and then all of a sudden vomit - like your DD.....
I was advised to avoid all forms of dairy when she was chesty or coldly, as that forms mucus. I also didn't give her bananas as they apparently can be mucus forming (bizarre, I know). No chocolate either.
Lots of clear fluids, water etc.
If you're into that sort of thing, I took her to a homeopath and that really helped her.
I also got her some cough remedy from the health shop, something like drosinula, for chesty coughs. You can give it to kids but need to check the dosage. She liked it anyway!
You can try goats milk, soya milk, rice milk etc - could be a little bit of an acquired taste, but worth trying.
You can get dairy free yoghurts, i.e. provamel yoghurts or soya yoghurts. Not quite the same as the others I know (my DD loves them too )
We have Dairy Free Sunflower Spread, you can get it in tescos.
Worth having a look in the Free From Section in your local supermarket or in health shop.
P.S. I find i only have to cut out the dairy when she is coldy, once shes over it I let her have it again. It might be worth you trying it just to see if it does make any difference, if you do and it doesn't, well at least you tried ....
MuppetsMuggle ...is dd on a brown mild steroid inhaler to calm her bronchitis down and her asthma or is she just on the blue salbutamol. buy omne of those facial steamers and get her to sit with her head over it and breathe through mouth. If you pu a spoonful of sat in it ,it makes its similar to salinity in nasal passages and the salt helps to make the mucous less viscous. If she is that bad ask the doc or consultant to provide you with a nebuliser and get some saline nebules to use when she is really bad. she doesnt have to be like this. you might have to buy the nebuliser, but its worth it. dont think they are available from gp..but the hospital might supply them. if not you can order them from your local pharmacy
you are better to get the nebulising solution ( saline 0.9% nebules)from gp on a precription so that it is monitored correctly, but you will probably have to buy the electrical unit. they are about £100 pounds and are not available on an FP10 prescription.
