3 is a young dog, just into his prime, with LOTS of energy. I bet he is a great dog, he is just bored. I bet he got a lot more exercise before your daughter was born. Believe me, I understand that, our 3 "babies" don't get nearly as much attention as they once did. Your husband is going to have to tire him out - maybe 15 minutes of playing ball twice a day, some hard running. I have a border collie who gets neurotic if she is not played with every day. We need to run her hard, she's a frisbee dog with tons of energy. That being said she is also an absolutely wonderful companion to my 2 1/2 year old son. They play together constantly. We laugh that if he ever makes it to the major leagues, its going to be because he got so much practice throwing the ball/frisbee for her when he was young. When your daughter grows up, she will thank you for having such a great dog for her when she was a kid.
