Hi, our breastfeeding journey hasn't been easy. From DS having a tongue tie for the 1st 2 weeks of life and losing allot of his birth weight. Afterwards he fed fine until last 2 weeks. He's just very fussy at breast. He sucks so milk comes out and then pulls away so it drops down his face instead of swallowing and then he will cry. He must be drinking some as he throws it up over me when I burp him. He wriggles and cries and sometimes screams at breast and I don't know what to do. My milk smells quite sour when he's feeding so I'm not sure whether it's something to do with my diet (I'm quite healthy in my opinion and take pregancare breast feeding vitamins) or if maybe he just doesn't like my breast milk any more. Any advice will be greatly appreciated. He is 9 weeks 5 days old. X
