Hello, on the 25th we will be four months old. He's been crying for three days now, especially at night, he cries, gets nervous, wakes up often. I feed him with breast milk, eats for two minutes then wants to go left then right and throws it off. I thought maybe teeth, but the gums aren't swollen. And his belly is not hard. I pick him up and he calms down. Now it's the weekend. On Monday we'll go to the hospital. But still what could it be?
