Hi Dr Fox,
Sorry for the long post, once I started I couldn't stop!
I have 3 DD's 2 of which appear to have some form of dairy intolerance.
DD1 has had problems with dairy since birth, she was a crying, screaming shouty mess until I cut diary completely out of my diet (she was EBF), when she became a calm and placid baby. (My DH developed a dairy intolerance in his 30's so the diet change was not too difficult!) We had several challenges whilst she was small with the same screamy shouty baby result. She was weaned with nutramigen and has been skin prick tested for a dairy allergy but with no positive result.
As she got older we were advised to reintroduce dairy which for a year or 2 she seemed to tolerate, then after she had been continent for a year she became constipated which soiling and unrinary incontinence The constipation is much much worse after any dairy (birthday parties etc) where she can be rolling around her bed allnight with tummy ache. We then have weeks trying to get her bowel back on track. (She has been seen by the paed continence team).
However we are now wondering if her intolerance is worsening as the frequency of constipation is increasing (she has 3 sachets of paed. moivicol a day with a firm-ish result (sorry if tmi)), and without any obvious dietary changes i.e. no obvious dairy (we have recently also removed goat cheese and goat butter, which she did previously tolerate). What would be the first food group to exclude to see if she has an additional intolerance? I ask as I understand soya is closely associated but we have been reluctant to do so until now as it is a replacement in so many of the products she can eat!
DD3 also seems to react go dairy with ezcema patches behind her knees and in her elbows when I have dairy, and has a slower poo transit time (but not constipation Yet!). She seemed to have the same bowel/ shouty baby issues initially (she is now 23mths) she is bf 2x day as she does not yet have milk (she does have goats cheese and goat butter). Would it be advisable to keep her dairy free (ish) or challenge her a little more and slowly reintroduce dairy?
To top it all our other DD has CF and has to have a high fat diet!! Food and meal planning is already a nightmare in our house!!!!
