As others have stated, the sprayer on this thing is so inconsistent. At best, it works 50% of the time. When it does work, it’s great. However, trying to get the nozzle up your squirming, crying baby’s nose, only for it to not work, is such a pain. I find myself spraying it in the air before my baby’s nose first. That being said, we end up wasting a lot of it, and it is already such a tiny bottle. I will say that baby prefers this over nose drops.See full review
