So Tibbs has been becoming more and more agressive it seems

My mom was down here 2 days ago and said he was trying to bite her hand. I thought he was probally just trying to play. But yesterday he bit the baby

The baby had fallen asleep on the couch and Bella was sleeping at the baby's feet. Tibbs was playing with his ball in the kitchen then all of a sudden he came running into the living room he started barking I shhhhhh at him so he hushed then I seen him jump on the couch I thought he was going to sleep to (They both usually sleep with Adam) Then I heard him growl and I looked over and about that time he bit the baby on his chin. I'm beside my self I do not know what to do I got Tibbs and scolded him 3 times and crated him. My husband is fighting me to give him away he said we can't keep a dog that's gonna bite our kid.

I love Tibbs he is my baby!!! My first Yorkie my love. But I agree he can not bite my 3 year old in the face especially for no reason. Please help any advice??
