Both of my DS's and I are cows milk protein intolerant (which is much more common than lactose intolerance). I used not to be too strict about it, but we are now vigilant. DS1 occasionally has a little bit of dairy sneak in, but I read every label and am very cautious about what I eat lest it upsets DS2. I found it took me 6-8 weeks to get past really craving it, but I did, and I have also found some great ways of feeding us all so we (mostly) don't feel like we're missing out (DH and I are dying for my lasagne!!!). DS1 likes rice milk to drink and for cereal etc. I find it a bit sweet (although that makes it great for cooking sweet things) and prefer oat milk, but we've recently found out that DS2 is oat intolerant so I've had to switch to rice milk.

We're all soy intolerant too, so none of that is consumed in this house either.
