Yu yee oil

It shouldn’t cause them discomfort tho. Hmm.. I usually applied one to two drops on my palms then rub till warm and pat pat around my LO’s chest & tummy. She seems fine to me tho. Maybe you can try reducing it to one small drops, rub longer then pat and see how? :)

Go those traditional herbal store and ask them for yu yee oil for baby one. They have one type that is less overheating cause sometimes their diaper will cover then plus swaddle the heat will increase alot.
