What Is It? Marfan syndrome is a genetic (inherited) disorder that affects the body's connective tissue. Connective tissue is the tough, fibrous, elastic tissue that connects one part of the body with another. It is a major part of tendons, ligaments, bones, cartilage and the walls of large blood vessels.
Your baby's first step toward mobility isn't actually a step at all -- it's a roll. When she's about 2 or 3 months old, she may flip from front to back. During tummy time (which you should supervise), your baby may lift herself into a push-up position and then start to rock back and forth or kick her feet. Then, if she's strong enough, those movements will send her rolling over.
Some babies can flip themselves from their front to their back as early as three months. But it's more likely that your baby will be six months or seven months old by the time she's strong enough to roll both ways. Her neck and arm muscles need time to strengthen first. Be warned that your baby will learn to roll over without giving you notice! You will need to be extra careful if you change her nappy on a changing table.
