My mom bought Manzanilla (oil) for my baby, she told me to use it whenever I feel that baby has colic and put some of it on my baby's hands, feet and back before bath time. I told her that our Pedia dont want us to use any oil since it will make the baby skin iritated. My mom told us that she used it on us but we grew up fine. How will I explain that I dont want to use it on my baby.

Manzanilla was found to be harmful to the liver. Please tell your mom that though you appreciate her concen you would rather heed the pedia's advise and spare your baby from that risk. Show her articles from google so she'll see that you are not making this up. If all else fail, bring your mom with you on your next appointment with the pedia, sometimes they just need a person of authority to tell them that.
