Good day, moms) Our daughter is two months old, her tongue has white coating. It's been like that for a month already. We visited a pediatrician a month ago, he said it's normal. Now there's more white coating on her tongue. And she keeps pulling her tongue out all the time. Is it bothering her? How can we get rid of it? We're breastfeeding.
