Good evening, my son has been having trouble sleeping at night for a month now, waking up every 6-7 times and crying to be held on his hands. I sit on a fitness ball and rock him for an hour or more sometimes, but I'm exhausted. My husband tries to help, but the son doesn't go to him at night and gets hysterical. He used to sleep perfectly before, after feeding and then he would fall asleep. Could kids react this way to teething? We have swollen lower teeth that aren't breaking through.
