I am a single parent with a 18 year old daughter, a 2 year old son and a one year old grandson. My problem is the boys have been biting, hitting each other and throwing things. My daughter and I are getting upset. We have tried timeouts, getting them to try to use their words, getting down to their level and talking in a calm voice, but nothing seems to work. I have been told that they’re just boys. Any ideas?
