I recently purchased a book called the fragrant pharmacy and I've bought LOADS of pure oils to start using.
The book says that the only oils safe for a newborn are;Roman Chamomile, German Chamomile, Lavender, Yarrow and Dill
They suggest the ones to use up to 12 months are; Mandarin, Eucalyptus, coriander, Neroli, Palma rosa, Calendula, Grapefruit, Aniseed + Tea tree
Am not sure what is on the 'not to use' list though sorry
