Six to twelve Months
I can really move now!
Around 6 months, many babies really get moving as they begin crawling, scooting, pulling up, and creeping. Make sure your home is ready for this new level of exploration with the appropriate safety measures. I suggest creating a “yes space” so your child can freely explore without your direct supervision in a safe manner.
Your child's brain is hard at work wiring all the necessary nerve connections for these new methods of transportation in her arms and legs, and she needs LOTS of time on the floor to practice. Any container your put your child in (bouncy seat, jumper, car seat, stroller, chairs with straps, etc) is directly opposing this goal and getting in the way of her natural development.
