Hi,

Oils that are particularly safe and relaxing to babies and children  are lavender, roman chamomile, vanilla.  But oils like eucalyptus, tangerine, mandarin, neroli, rose can also be used for  children.  These oils should be used in a diffuser to scent the room while you put the babies to sleep or place a drop on a cotton in a corner of the bed where it will not come in direct contact with the babies. I prefer the diffusion method as it is very safe for babies.  The cotton method can be used for children above the 2 yrs of age.
