My baby is 4 weeks old. He is only breastfed. He feeds for 10-15 mins. Since a week he is being very fussy towards end of feed and pulls away. He wants to feed but won't when I offer him instead he starts crying. I put him on other side thinking milk flow could be low but he is still fussy. He also sweats while feeding and breaths heavily after sucking for 4-5 times. Also there is yellow discharge on his right eye. Are these problems inter related? I'm worried if he is fed well.
