By this week, your baby will probably be able to crawl well on her hands and knees, with her trunk parallel to the floor. (Many babies try to crawl before, but master the skill only now. Some babies bypass crawling altogether and go from scooting to standing.) She may even be able to crawl up stairs.
At this age, your baby can sit confidently and may even walk while holding onto furniture, possibly letting go momentarily and standing without support. She'll take steps when held in a walking position and may attempt to scoop up a toy while she's standing, too.
Those magical first steps toward independence and lots more exercise for you are just around the corner, if they haven't arrived already. Most babies take their first step sometime between 9 and 12 months and are walking well by the time they're 14 or 15 months old.
