HELP!! Lump under her nipple.

Nikki

slightly freaking out.

I just discovered a pea size, hard lump under my 4 month olds nipple.

I know this is normal for breastfed babies but, I stopped breastfeeding over a month ago.

Anyone ever go through this with a formula fed baby? She’s going to the pediatrician tomorrow but, looking for help in the meantime to maybe ease my mind!
