She seems fine when i have dairy but cannot have it herself, i have lowered my dairy intake quite a bit (used to have cheese EVERY day etc) and she is a lot more settled now.
I am finding it ok as we eat a LOT of fruit as a family but she's starting to be interested in cereal, pasta, cakes etc and i would like to be able to make a lot more 'healthier' options of these things for BOTH of my girls, also that DD1 gets a lot of variety that DD2 cannot get due to products containg milk solids or butter etc.

Thanks for your help everyone.
