Hello everyone! Girls, something's up, our baby hasn't been eating formula for the last eight months. She eats 70-100 ml and that's it. She eats porridge but not very much, she only eats purees (cucumber, broccoli...). Sweet purées of cottage cheese, soup, I think she eats them too. How do we stop her from refusing formula altogether?
