I have 5 month old baby boy can I. feed expressed milk to my baby and how much time it wiill be store please give me suggestions

A. yes if your baby is not able to latch it properly then you can use breast pump to extract milk and give it to your baby E and without refrigerator you can store it for one or two hours and in refrigerator you can use it for 7 to 8 hours also so using breast pump will be really helpful
