Hello everyone. I have such a question, we're on mixed feeding, we eat more formula milk, straight milk is very, very little. That's why I have a question, how much formula should the baby eat, on the box with the formula it says from 3 weeks already 120 ml baby can eat. I think this is extremely much))) How do your babies eat on mixed feeding, and how do they eat those who only eat formula?
