How long can the teeth stay out? We're in full swing. The temperature is up to 38 for three days, a couple of droolings came out, crying/fussing so much that he even gets him turned off. He eats, sleeps thankfully well, maybe wakes up a few times at night, hiccups, gives him a pacifier and falls asleep again. His gums are painful, it doesn't look good. The teething aids cooled down a bit help, but I lower the temperature at night. How long can this picture last? How was it with you? If there are photos of the gums, I would be very grateful
