At 17 weeks your baby is approximately 5 inches long from crown to rump, and weighs approximately 5 ounces(about as much as a turnip).
Its skeleton is mostly rubbery cartilage, which will harden later. Your little one is refining sucking and swallowing techniques for the day he first encounters a taste of milk.
Note: Every baby develops a little differently — even in the womb. This information is to give you a general idea of your baby's size.
