Still, if you've got very curious toddlers those boxes need a little something extra since they do not have a lock on them. My children were drawn to essential oils so I had to come up with a more secure way of preventing them from accidentally opening up the bottles. Let's not talk about the day that my one year old dumped an entire bottle of frankincense on my bedroom floor! This is why I LOVE and recommend ALL parents get these child safety caps. They are super easy to put on your 5ml or 15ml bottles and take all of 5 seconds to put on. The best part is that now I'm able to keep my essential oils in the rooms I use them the most...some in my kitchen, bathrooms, bedrooms and living room! Woohoo! Cause reality is out of sight, out of mind. Having the essential oils throughout your home will remind you to use them when they benefit your family the most!
