Breastfeeding

Hi y’all so my baby is 4 weeks today, I wanted to breast feed from the stsrt and was having trouble latching so we turned to formula however I was pumping too! I then stopped pumping but still tried putting her to boob before feeds and when she was hungry, she has been latching today I do still have milk coming out but when she goes on she will just fall asleep is this normal but I’m sure she is getting milk otherwise she would be screaming that she’s hungry right? Or is it just a comfort thing for her at the moment?? I’m stressed thanks in advance mommy’s!❤️❤️

And has anyone else had this problem and then successfully breastfed?
