They have ones that are safe for very young babies, however even they say what age is best. I really REALLY recommend talking to pedi. Theres a risk the babys sinuses will swell shut and the baby could suffocate.
Also instead on putting it on the chest you could try on their feet. I heard it works best and I’ve been doing it on my babies feet since se was tiny. Now I use it on her back, chest and feet.
Baby chest rub is best and I love it ❤️ I have the baby Vick’s and also the Zarbee’s brand. I asked 3 different doctors and 2 nurses and 2 docs told me it was fine also the 2 nurses. Everyone’s recommendations are different. If you decide speak to your doc about your baby first.
