Yes, totally can relate
!
I suppose if you end up finding out that milk/soy *is* an issue then you'll really have to get your head around how to get calcium into him - BUT it may well be that the trial shows that he is fine with them and then it will have only been two weeks of not eating yoghurts etc. I've been giving Ben 2-3 smoothies a day this week - and I've snuck all sorts of fruits and veg in them that he wouldn't normally eat
- so maybe take advantage of that. I also made him a thick 'yoghurt' with the creamy part from a can of coconut milk, some frozen rasberries and a but of honey. He really enjoyed it.
Things like fish with soft bones (tinned salmon, sardines etc), sesame seeds (so if you can make homemade hummus with more tahini to bulk up the sesame content), and the fortified oat milks will provide calcium in the meantime - but I doubt two weeks of not eating the normal amount of dairy would make any long term impact.
