It’s ok for a couple of days. I find it works fantastic if you put it on their feet before bed.. I use the bear rub one as it’s not so over powering. A couple do have a age limit on them just check with chemist

I would think it is but would check with a health professional first.

I found Vicks to be quite overpowering so I used to put it on my kids feet, and yes its safe to use over a couple of days. Having said that, I only ever put it on at bedtime

The moment my baby start sneezing and had runny nose, I applied Vicks Baby Balsam continuously until a few days past he’s well. I applied it to his chest, back and his feet. I also use Fess Little Nose Saline Spray for his blocked nose.
