Baby is 3 weeks old. was calm, feeding great for first week. Then I took antibiotics for stitches infection, baby became fussy,windy green poo. have got back to yellow poo by feeding from same side 2-3 times in a row but now baby not satisfied, only good latch when there is foremilk, then pulls away to just comfort suck on nipple. as soon as i give new side, explosive poo, fills up on foremilk, stops feeding after five mins, only sleeps for half hour through the night then awake for 3 - 4 hours. gaining loads of weight. SOMEBODY please help me. Have cut out sugar and caffeine today, dont know what to try next other than adoption!
