From day one, your baby has maintained that special spot in your heart. But by month seven, he knows it and he intends to keep it that way. Keep in mind that it's good for baby to start maintaining some control over his environment, but as his parent, you need to determine how far he can go. He can sit without support.
Baby can stand while holding onto someone or something.
He can pull himself up to a standing position from a seated one. Baby walks by holding on to furniture. Baby plays peekaboo. Baby waves good-bye. All babies have their own internal developmental timetable.
