OK - DD is 2.2. She was unwell a week or so back, and was vomiting every night (usually just once, after which she was fine). Thanks to the wisdom of a mumsnetter, we figured this was a secondary lactose intolerance and have moved to giving her only lactose-free milk. She is still eating cheese, butter (although less of this - she used to be a fiend for it) and probiotic yogurt, so I have no real worries about her calcium intake (and she is drinking the lacto-free milk too).
Since we made this switch, though, she is a different child - more energy, vastly improved appetite (actually finishes meals!), brighter skin and eyes. She is also quite small, but seems to have grown. She also suffers from chronic constipation and has been on Movicol for almost a year - but since taking her off milk, she is doing very soft poos, and I've decided not to give her any movicol for a couple of days to see what happens. I know usually it's the opposite effect but some research seems to suggest a link.
Now, I've a couple of questions: Has anyone else had these experiences? How do we tell if it's lactose or milk allergy? As she's over 2, is there any need to attempt to reintroduce cow's milk? Has anyone had the link to constipation?
thanks
