Girls, can you please tell me how to introduce flour? I want to give pancakes of all kinds, we're currently only eating mashed vegetables from the jar, plum and porridge. I'm afraid to give them in pieces, they don't seem to chew properly. How do you correctly give allergens (kiwi, egg, tomato, etc.) Share your experience. How to teach a child self-feeding? Do you feed food like in the photo? Is there a guide with recipes for every day?
