Thanks for your posts.

I have exhausted all other options (besides AB's) in terms of vaporisers, warm air, salty water, etc and she's only 13mths so I can't yet teach her to blow her nose, well not efficiently anyway..... so she's had a green snotty nose now consistently for weeks which says to me it's a sinus thing I suffer sinus problems.
I might take her to an ENT (ear nose throat) doctor who can look..... just help get rid of it all.

I am considering AB's next week too..... I gave 2 teaspoons in a sippy cup of water last week but she only took a few sips anyway so she never really ingested much anyway. So no big deal.
