My little boy Brutis has been doing this all day today! He has never done this unless he was nervous. He has nothing to be nervous about today as we are home and all is well. I have heard that this is a sign of pain. If he is still doing this in the morning...we are going to the vet. What are your experiences with your babies doing this? I'm really worried about him. He acts fine as far as walking and everything but he didn't come into the kitchen with my other two babies for a treat.
