Bree • 25 years old. Madly in love with my king 💘. Have one healthy baby boy who just turned two and one on the way! 🍼👶 2 angels in heaven 👼👼.

My milk is just coming in now.. I developed swollen armpit lumps or lymph nodes I have a call into the doctor. My breast themselves are sore but not hard or anything has anyone else experienced this.
