Mommy, who has been through it all, anyone who's experienced this, I've noticed a decrease in my daughter's appetite for the past two days. When I give her a bottle, she starts eating with pleasure, then she starts burping in her stomach, like that. And then she immediately refuses to eat, yesterday and today I'm struggling, worried, I write to the pediatrician, she says gas or teeth, but what about the stomach? ??‍♀️ It's exactly that sound when she wants to eat, but she doesn't eat. For the second day we haven't met our quota ? Although she poops and pukes, it's unclear what's going on.
