My husband and I both love food and I love cooking. BLW has meant LO has been exposed to different textures and flavours since the get go. He is a bit of a pig but is beginning to show preferences for things the older he gets. He HATES toast. I've tried everything on it: cheese and tomato, cream cheese, butter, peanut butter, avocado... He eats (sucks off) the topping but spits the toast out every single time.
In nursery he eats whatever he is given - sweet and sour chicken with rice, pasta bake, baked potatoes, vegetables... Whatever. I think he likes nursery food because it's full of flavour. He's never tried purée and isn't keen on simple veg. When I cook I use loads of veg and he'll eat the lot, but I use sauces (homemade) and herbs and cheeses like Parmesan and strong cheddar. LO rarely gets bland food and when he does, he messes about with it. So yeah, I think babies get used to the foods you give them - the only food my LO has ever really refused is my husband's cooking LOL.
For my LO, my aim is to never give him anything I wouldn't eat myself. When we have scrambled eggs for breakfast, because I don't add salt to his, I flavour them with plenty of unsalted butter, pepper and herbs or cheese. Same with mashed potato and any other 'bland' food.
