Chipmunk milk?

Briana • Mommy to an angel 👼🏻 6.9.16 & and my babygirl 3.3.19 🥰💕

Does anybody else’s babies keep milk in the inside of their cheeks? 🤣 I don’t know why my daughter does this lmao but sometimes she’ll end up swallowing it later or just spitting it out. Not throw it up, literally just open her mouth and and let it spill out slowly. U can see it on the side of her cheeks sometimes. Is this normal lmao
