cow and gate comfort milk, its for colic or constipation, all the brands do a version of it, but was told to go on that as its the best one, omg its amazing, he doesnt even drain his bottles now, after being on sma hungry baby and still draining 5oz before even 4 weeks old and wanting more every 2 hrs. sienna was on cow n gate, but i used sma with elila and chloe and they were fsb, so thought id use that this time, i have to say i wish id gone on c&g from day one, only trouble is eneding this comfort one long term, his arse stinks lol
