I got my tongue done and did not know I was pregnant and she was fine the dr told me it was ok as long as it did not get infected but I ain't know if it was the same @santistevanmommie
It shouldn't mess with your milk at all. The molecules are too big to pass to your milk. The only way she would get sick is if you got an infection in your tattoo
Although most tattoo shops won't do it if you tell them you're breastfeeding it is safe. The la leche league recommends waiting until a yr pp so there is less chance of infection
