By this age, most babies can roll over in both directions — even in their sleep. Some babies can sit on their own, while others need a little support. You might notice your baby beginning to scoot, rock back and forth, or even crawl across the room. Some babies this age can pull themselves to a standing position.
How long should 7 month old play alone?
The older a child is, the longer he'll be able to play alone. For example, at 6 months, a child may be content by himself for 5 minutes; at 12 months, for 15 minutes; at 18 months, about 15 to 20 minutes; and at 2 years, for about half an hour.3 oct 2005
