It takes approx. 36-40 weeks for the baby to be fully developed. Before that, the baby is premature and might have to spend some time in an incubator.
Gynecologists from the USA have separated this concept into 4 stages: 1  early term 37-39 weeks of pregnancy; 2  completely full-term 39-41 weeks of pregnancy; 3  late-full-term 41-42 weeks of pregnancy; 4  postterm pregnancy more than 42 weeks. So, after the 37th week of pregnancy, the child is considered full-term and ready to the birth. Of course, he will be not as large as children who are born on 41th week of pregnancy, but all childâs organs are already created and capable to be full-functional.
