my grandson

My grandson is 3 years old his mom and dad are not together.Lately he has been cursing like a sailor using the f word a lot and other words.We DO NOT curse in our house and he lives part time with us, his brother (who is 10) and his mom.None of us curse.He is also very violant he broke his other grandmas nose by throwing things at her.We have tried soap.vinegar,spanking and time outs we are at our wits end.Any suggestions will be very much appreciated.

Therapy.... get this child into some therapy, but before you do you should check in with the childs primary care physician.  His doctor knows him better than anyone and would be able to point the family in the right direction.
