I am very strict with regards to my baby's hygiene. I give her daily baths, clean her umbilicus thrice a week, swab her earlobes every after bath, and clip her nails as needed. But when it comes to cleaning her tongue, I am having a hard time. I use wet towelette or a baby tongue brush just to scrape off the milk. I read an article about this and I learned that it is important to prevent bacteria build-up and tooth decay. Since my baby is only 3 months old and doesn't have teeth yet, is it necessary to brush her tongue often? Can it cause trauma or fear on her? Thank you for reading.
