Help!! oat intolerance question,,,,

[simpson]

DD (16mths) is intolerant to dairy, soya and now oats is the latest one.

However things still don't seem to be normal on the poo front iyswim.

If she is intolerant to oats, do I have to avoid barley too?

As she has been eating barley every day in her breakfast.

TIA

Sorry I don't have an answer but bump for you as you must be having a nightmare with feeding.
I was intolerant to dairy as a child and didn't even taste ice cream until I was 10 years old, but I did grow out of it, so there is a light at the end of the tunnel for you hopefully.
