Not sure if this board is appropriate for whinging but it's relevant.
I just posted about by 13 month old CMPA baby.
We went to DH's family for dinner today where lunch was pasta in cheese sauce. DH asked if it was dairy free cheese sauce and it wasn't so he said that DD can't eat it and he was told "but it's cooked". He said that she can't have it so she was served plain pasta and a banana for lunch.
Same at dinner with the Yorkshire puddings... "but it's only a little bit of milk and butter".
If it's too difficult to cater for her, tell us and I'll bring a meal along or don't invite us.
