I used to find many signs of teething in my son, but everything was in vain so far. We have none yet. I say that we already have a stable nighttime sleep from 8:30 PM to 7:30 AM with 1-2 feedings. A couple of days he's been very capricious during the day, crying and crying, almost no hands in his mouth, I'll say right away, he chews toys as usual, except for the nipples from the bottle he gnaws straight out, he scratches the left earlobe, the doctor said it might be possible that teeth can irritate nerves, I noticed during the day that the gums swelled down and slightly red, they were straight pink-white.
