DD just had another palate-related surgery. She was born with cl/cp so we know the soft food diet all too well.
I have one word, ok two words: food processer.
DD doesn’t love it, but she does get tired of the same old soft foods as you mentioned. Last night we had spaghetti and I just pureed it. She really liked that. I think the hardest part is that DD is supposed to only have things that require no chewing. She can’t even have mac n cheese yet. She was craving something besides sweet stuff.
What about mashed potatoes (you can always thin them out more than normal). Any type of soup as someone else said, just puree it more. DD loves baby food for a change. Your DD might like some of the fruit ones, maybe not the veggies ones although DD likes some of them.
Pureed sweet potatoes, soup from cooked dried beans (you could puree the beans too), any type of shake (which you could make from whatever fresh ingredients you have/she likes whether fruit or veggies or both). Pediasure is always a back-up though it is not my first choice, but if your child is getting hungry it can help with that feeling of hunger.
HTH and hoping for a quick recovery for her.
