Milk seems to flow at the right rate, it drops out into his mouth but not too fast. He definitely likes the formula as occasionally he'll guzzle a bottle with no issues, but most of the time he's trying to sit up and moving about - it could just be that he's incredibly distractable, he is spirited after all...just difficult to get him to take a proper feed on these occasions so I can't get him on a proper schedule. He's still demand fed really...
