Hello, there's a problem, the child started eating poorly, we feed him yogurt, he starts eating crying then takes again, at the end he falls asleep, poop is true it became like porridge (we left from triple comfort) legs don't squeeze, doesn't click, lies smiling until you start feeding, I don't know what to do and pacifiers and bottles change, give him Hi-Lac Forte
