Excitement describes baby now - excitement in discovering all about the world.
Make sure your house is baby proofed - electrical outlets covered, gates across stairways, and swallowables and breakables out of her reach. She is becoming mobile - rolling, scooting, crawling. She may even be pulling herself to a standing position by holding on to a safe table or couch. She likes to shake, bang, and drop things - just to see what happens. She likes to help in feeding, but not always with the best results.
