Cooking for baby

Hi mummies, can I know how do you all handle the remaining fresh vegetables like pumpkin/spinach/capsicum/tomato after taking out a portion for baby? Baby eats so little each time and it’s not very ideal to give the same ingredient everyday right? For the fish/meat can keep freezer so no issues. I don’t cook for myself at home, only cooking for baby, so find it really hard to reduce the wastage. Always keep the fresh produce until not fresh or spoil. I used to prep all at one go, blend and freeze in cubes for all the veggies, do you all do this too?
