I exclusively breastfeed my 2 month old baby. Sometimes he rejects my breast so I pump. Can I mix milk of same day or between hours into one bottle? Should I wash the tunnel after every feed or can I store in the fridge with tunnel n use again

A. thank you for reaching out to us with this question it's always better not to mix the milk always date and leave it in the refrigerator and use accordingly just make sure you invest in some good milk bag that that are designed for storing purposes and I was just always wash and use after every pumping session
