i have a 13 mth old daughter that absolutely refuses to drink cows milk. previously my other 2 children have made the transition from formula to cows milk at 12 mths with no trouble at all. i have tried the toddler formula, she refuses that as well. on the odd occasion that she has drunk cows milk, cos we were out and there was nothing else to drink, she wound up at the end of the day with diorhhea and became very mucousy. she hates ice cream and wont have much yoghurt and cheese either. she was a reflux baby, so i dont know if this might have anything to do with it? currently i still have her on formula just so she gets some form of nutrients. does anyone have any suggestions or been through this themselves?
