Breia • 24. Married. 3 blessings all under 6.

My 10 month old has this on her tongue, it doesn’t seem to bother her and I’ve sent a picture to my midwife but she has never seen anything like it. Can anyone share if they have seen this before or knows anything about this? She’s breastfeeding and supplementing with Enfamil, and no changes to either, or her diet.
