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.
So the reason for the Back to Sleep issue is that it has shown to decrease the rate of SIDS (Sudden Infant Death Syndrome). A baby can start sleeping on there tummy when they are able to roll over, typically 3-4 months of age.Typically start on the back and if they roll....then they roll. A baby can have some tummy time (around 5-15 minutes) supervised around 1-2 months of age when the baby is able to hold up their head.ou are doing the right thing! Never allow them to sleep on their tummy unless you are watching them until they are 1 year old or more. SIDS is a serious concern and the risk increases when the baby reaches 4 months and starts to be able to roll over.
