I think it was lavendar oil works. Let me check on that, or maybe someone else here knows. If I remember right you put a tiny bit of the oil on your finger and either put it on the nose ( almost none does the trick) or was it on the chest as a swipe.. I think it was lavendar oil, but it releaves anxiety and calms them down. Whichever oil it is, its also in the dog calming plug in they sell for dogs for dogs with seperation anxiety. If it calms them down, it sure should work for your baby.
