I only mention it because I dont want to worry someone whose child is going through treatment IYSWIM.
Of course you are worried. It is sensible to take precautions. Do you know what her neutophile count is? It becomes helpful to know this as you will soon begin to understand all the numbers. Knowing her count can help you work out how at risk she is.
Is she neutropeanic all the time 'just' on the low side?
I became a total clean freak whilst DD was neutropaenic. It helped me feel in control but DD was more at risk from internal infections. All the parents knew this but we all still cleaned like demons
During health scares its awful. All that stuff about swine flu!
All you can do is take sensible (or not so sensible in my case!) precautions. Good hygiene, careful when handling/preparing food and I would avoid public transport. Take advice from her medical team re playgroups/school etc.
Do you have a protocol to follow if she gets a temp? We used to take temp, take it half an hour later, if it was above 38 ish take her in for antibiotics. I dont know if this would apply to your little one.
If it does I would advise ditching those bloody awful digi thermometers and get some tempadots from your nurse (the disposable things they use in hosptial).
Its very hard. Try not to fret. I found being very organised helped me to cope - not sure why - control issues I suppose.
Good luck and best wishes.
