During this time your baby is continuing to learn about his world. He will probably start to crawl around and may pull up on furniture. Make sure his world is safe.
Sit up without help
Stand up while holding onto your hands
Stand up on your lap and bounce
Fuss if you take something away from him
Recognize a familiar voice
Eat a cracker by himself
Play pat-a-cake
Play with his hands and feet
Hint:
Literacy (being able to read and communicate) begins now! Your child needs to be held, talked to and given a calm, loving home.
Provide cloth or cardboard books for your child.
He may be afraid of strangers and not want you to leave him. If you must leave him, remember to say "good-bye" and remind him that you will come back. He still has to learn that objects-out-of-sight will appear again.
If you need child care, be sure that your child receives quality care. Your child's caregiver should be providing age appropriate activities for your child as well as a safe & loving atmosphere.
LOTS OF FUN!Play games with your baby like:
Start A Healthy Teeth Habit Now!After meals, first teeth can be wiped with a clean, damp cloth or brushed with a very soft, tiny infant toothbrush moistened with water. Avoid toothpaste until he learns to spit it out. It could make him sick.
Well Baby Check-ups: 6 months, 9 months
Read to him daily. Show him pictures in books and point to and name the people, as well as other things in the picture books.
Roll a ball to him. As he grows and gets used to the game, he will try to roll the ball back to you.
Hide a ball or other object under a blanket while he is watching you and let him find it. He will learn that objects out-of-sight don't disappear forever.
Give him a metal pan and show him how to bang on it. Let him have fun making the sounds. 
Place him on the floor on his stomach. Encourage him to move toward you by clapping your hands and laughing. Crawling is needed to develop other skills.
Place round oat cereal on his highchair tray and let him practice picking it up and putting it in his mouth. His eye and hand muscles will get strong and begin to work together.
Let him practice dropping unbreakable things like soft balls over the side of the bed or high chair in order to learn what happens when he drops something.
