When is the first tooth gonna come?

Little Andrew drools so much and it makes me wonder where on earth the drool comes from?! The amount of saliva is just crazy! It's never ending wiping it off this fingers and his mouth, and it's so much that it even drips down to his neck and rompers!

I wonder if his first tooth is coming out soon. Besides the drool, he BITES everything- from his fingers to anything that he can get his hands onto.

There is no fever so far. I read that ear pulling and cheek rubbing are also signs of teething - he tugs his ears when he is falling asleep and will rub his face on us whenever we carry him.

I am so excited and can't wait for the first white cap to appear.
