Breastfeeding but LO still hungry

Kela

Hello ladies my son is 1 month and 9 days old and let me just say BF has been hard since day 1 . He has had a hard time latching and staying latched so we supplemented by feeding him formula and pumping , well as of recently I tried to BF he out of the blue and he was able to latch but not for more then 5 mins . Now I BF him everyday multiple times a day because that is how I want him to get his food however sometimes he will get enough and fall

Asleep on my boob then wake up and still be hungry . Or He will feed from both sides and still be hungry. Just curious if any of you BF mommies have any advice for me because I feel as if my babe isn't getting what he needs and the amount he needs .
