When I latch how do I know if my baby is shallow latch or deep latch ? When my baby latch the milk always end up on her cheek or flow down to her ear is it because she is not swallowing?

Seemed like yr baby isn't latching correctly. There should be no milk on her cheeks at all. You may need to establish a good latch and ensure yr aerola is inside baby's mouth and when shd u put in? When baby's mouth is wide open.
