Essential oils and babies

So I’ve read there are some essentials oils that you can use for baby but you have to dilute them very much so as not to cause irritation. Oils like lavender, rosemary, chamomile etc.

just out of curiosity, what do you guys think about using oils for baby for example to decongest sinuses or soothe?

I have a 2 wk old. What are some concerns you’d have as a parent?

Would u use for your child instead of OTC medications or steroids?
