Hello everyone) I've been asking too many questions) Could you please tell me if anyone has had such an experience? The baby eats half of the formula, then raises his arms back and bends over, he doesn't want to take anymore, he's capricious. As soon as I remove the bottle everything is fine. It happens every now and then. We switched to a couple of days on a new brand, but it's the same brand, just brought from Europe, not bought here. The formula is different from ours. Could this be due to the formula? Ultrasound OBP was done recently, everything is great
