Sorry you got bad news. You deserve to be able to breathe a little after so much struggle. You really need a nice family holiday earlier than what the doctor says. Maybe you should look into booking an appartment with a kitchen so you can prepare your daughter's meals. Not ideal on a holiday, but better than no holiday.
THe problem isn't the cooking we don't mind that, it is the ingredients. Surprise, surprise, not everything is labeled on the pack so we have to go on brands that are guaranteed not to include. This is not possible outside of Finland as the brands and laws for packaging changes. We can get by perhaps for a short time with a very limited range of fresh vegetables and meats perhaps.
