The baby hasn't pooped for two days and has been having many loose stools with difficulty, it's bothering him all day, this has never happened before, what should I do? We don't have glycerine candles in the city, I looked everywhere, he's crying really hard, I haven't given him any food yet, I haven't noticed if he's constipated.
