Girls, hello everyone, anyone have a child who has stopped eating, I don't even know what to cook anymore, he used to eat everything, meat and so on. Now he's completely lost interest (( Maybe it's some kind of period for the kid? I don't know what to think about, I thought maybe teeth, but looking, there's silence from his teeth, he prefers to drink popsicle or green tea now, I thought he might be overeating this and that, one day I decided not to give him, he ate such food and still like that...weakly very little
