teething period could result in drinking/ eating less, more drooling, more chewing on things, midnight cries, wakeup in the middle of the night(s), extra cranky, sleeping less, diarrhoea, sudden low grade fever.
They might not come all at once, may be just one or two symptoms at once.
My boy used to go for 4hrs refusing to latch and keep crying on and off. Cant force him also... Its worrying. but still considered normal.
