My bub is now 2.5years and has outgrown the LI. On top of the LI she has quiet severe reflux and ended up hospitalised a few times from aspiration pneumonia. J could not have dairy until she was around 12months old and with slow introduction now has a completely normal diet. Dairy and tomatoes made her break out in a rash especially on her face, have explosive stringy green poohs and been really unsettled and distressed.
With the BF I had to cut out all dairy and the odd occasion I tried something I'd soon know about it. At around 7-8months I started introducing dairy again and was able to eat most things in moderation.
