Hello, has anyone experienced this? The baby started crying, sucking on mucus, went to Lori, she said it was slightly swollen in the nose, looked at the ears and mouth, said the problem is going to the teeth, prescribed drops but a week passed, the baby still cries, I can't suck anything out of the nose anymore, why doesn't the crying go away, the nose seems to breathe when asleep, the mouth is closed when sleeping, what should I do?
