seriously bad mama momma moment

Yesterday P was chewing on the electrical cord (plugged in) that connects to the baby monitor (he likes to play with the receiver). Anyhoo, he had unplugged it and was chewing on the plug itself while plugged into the outlet. He pulled it out of his mouth and looked at it funny. So, I tested it and sure enough--it shocks you like a battery will if you stick it to your tongue. He's acting perfect. My tongue is still a lil' tingly today. Gosh, I'm worried!! I should have intervened more quickly--stupid momma!!
