Ds is 1 on Sunday and I'm not sure whether to switch him over to cow milk. He was just under a month early and while he has been a bit behind on gross motor skills(no crawling or pulling up but great bumshuffller!) but weight wise has never been premmie as 91st centile. Not sure if I'm being PFB in worrying about the cows milk as no reaction to having used it in his food so far.
