starting to wean off the breast now, begun to do a formula at 7.30pm before bed, hoping it'd help him sleep thru. ooooh how wrong i was, he is getting up ten times more with wind and bellyache. he is constipated now as well. he chews the teat, puts it to the side of his mouth like a pipe and all the milk dribbles out, he plays with the bottle pushing it away then when i take it from him, snatching it back to his mouth. need to move to bottles now as im going back to work, getting v disheartened. im using avent bottles with 6month level teats and aptamil follow on milk, should i try different milk, bottles or slower teats. thanks in advance
