I hope that your baby is okay!
Starr died because she swallowed the wood of the pencil. It was actually a pink colored pencil

It got caught in her intestine and blocked it up. By the time the vet finally operated on her (5 days and 1 lb. weight loss later) she bled to death after surgery, after he had us take her home.
If there is any indication that her tummy isn't working right, vomiting, not eating, not pooping, get her to a vet and let them know that she chewed a pencil and what happened to my baby. I'm not saying that your girl is in any danger, if she chewed the wood up really well then it's probably okay, but her size worries me. Starr was a 5 lbs 3 year old adult yorkie. At least call the vet in the morning.
BIG hugs
