Mama is a little bit of paranoid when it comes to bacteria – she cleans everything before i used them – and in my bedroom – she uses tea tree oil products to clean my stuff – because they said that it removes bacteria. But mama said that tea tree oil is also used as an antiseptic, anti-bacteria, and it fights off various fungi and different types of germs and even acne! So if you are like mama – and want a healthy kiddo – try using tea tree oil – it smells a bit funky to me – but mama said it smells awesome!
