Girls, I would like to express myself, my friends also have babies, and acquaintances. And they know that the little one doesn't want formula milk at all. What do they say so simply? Like "YOU SHOULD BE FEEDING FORMULA MILK". "Do you understand that if you don't feed formula milk until a year old, she will regress in development?" Well, I'm not stupid, I understand that formula milk is important until a year old. Well, the baby doesn't want to eat formula milk, I am already in a panic. We have already changed the formula and another one, but it doesn't work. Well, I can't do anything.
