Babies cannot have honey until after a year old!!!
At so young baby shouldn't be drinking anything but formula or breastmilk anyway.
You can try streaming up the bathroom and taking her in there to breathe the steam. Or if it's croup they say cold air helps. If you have a humidifier use is. Usually helps to keep baby elevated, they breathe better upright than in their backs..
Please don't give your newborn honey and lemon or any other concoction. That's bad advice.
