Ok so my son is 1+3

2 weeks old and he has never really had a problem with latching. But I’m worried he is not getting enough because he will unlatch himself and act like it doesn’t want anymore. Today he nursed on my left side for 20 minute and 10 from my left then stoped. But became very fussy and would settle. Son I passed him to his dad and I pumped 1.75 oz out the right and he drank all of it from the bottle I really want to breast feeding but it’s becoming stressful what do I do???
