There is a Claryntyne (spg?) for children from 1yr - DD has had a few doses lately for hives.

I know how frustrating the cold/runny nose can be - we seem to have the cough version. DD was so healthy until the cooler months in CC hit. I'm not blaming CC, but it certainly ups the exposure, wears her out, and it seems we always pick up the cold/cough/runny nose. I'm also lucky she's generally a happy sick kid too, you wouldn't know she was sick if she didn't have the nose/cough. We give DD a probiotic in her water every morning, and she see's my chiro every 6 - 8 weeks if I can swing it, but otherwise I just try to keep up the fresh fruit and vege, keep her as warm as possible, and try not to over do it too much on days off if she's not 100%. It's frustrating, and I hate taking her in with a runny nose or cough, but if we stayed home every day she had a runny nose we'd hardly ever go. I'm talking clear runny nose too. Some mornings it can be more yellowish but the GP said it just pools overnight and usually within an hour or so it's clear. We've also had major ear probs too but seem to be on top of that for the moment

Sorry I probably haven't helped much, but wanted you to know you're not on your own. I really hope the nose dries up soon and she's right as rain!
