Can you apply this on a 7 week old baby?

Hi Cynthia, thank you for your inquiry, we do not suggest using this product on babies under 4 months, instead for young babies under 4 months, apply to your chest and let baby inhale soothing oils that way, or apply on a tissue and place this under their pillow/sheet. We hope this helps.   if you follow the link https://www.babyonthemove.co.nz/store-locations/ this will take you to our online store finder.
