the actual baby is usually developed on the outside by probably 4-5 months, but it actually takes the full 9 months for all the babies organs to develop. the lungs are the last of everything to develop taking till about 37-38 weeks.

If that were true, don't you think then that premature birth would be no big deal!!!
The lungs are the last to develop all the way up to delivery! The following is an excerpt from the site below:
Babies born this trimester have an great chance of survival with all major organs functioning! Consider the third trimester as the one where the finishing touches are added. By the beginning of this trimester your baby will have all of his/her bones -- 300 to be exact! Now he'll be building fat stores and muscle mass. Your baby's hair will be growing, replacing the lanugo that protected her skin in the womb. By the end of this trimester your baby will be approximately 7 pounds in weight and about 20 inches long. Her lungs mature right up to birth so don't become too anxious to deliver early. Each day in the womb (up to 42 weeks gestation), helps prepare your little one for the world outside! Again, accept our congratulations! We wish you all a safe, healthy, and happy birthing experience!

Babies need all that time 40+ weeks to be healthy and have the best chance at life...DO NOT BE IN A HURRY, you can't rush perfection!

A baby is developing in the womb for the first 10 weeks. Then it's completely formed and starting to grow and perfectioning what is already there.

close, but not completely true. the baby has all its parts by the end of your 6th, not 4th month, but it still has a lot of actually developing to do.
Every organ and body part is there, but they are not fully functional. The lungs are little buds, incapable of functioning, untill somewhere around your 33rd to 35th week. the heart, though beating and strong, is not strong enuff to pump its own circulatory system without help. And the brain is still making rapid new neural connections constantly -- even up to a year after birth! its really only the last two months that the baby starts to gain weight and stops the majority of its physical development. But there is a reason we dont deliver at four months!

Don't let anyone fool you, it's 40 weeks, which to my calculations is 10 months.
You should really check out the development of a baby.
Maybe google it or something.
I watched it once on Nova or something.
Really interesting.
So no, the baby is forming the entire time they are in the womb.

I think its the first 5 months, then after that, the baby just gets bigger....Baby also grows in size as he's developing.

They have all their parts and organs by 11 weeks. From their all these parts mature and then really after 32 to 34 weeks nothing much happens . The baby is just getting bigger and gaining weight. My son was born at 34 weeks and everything including his lungs were fully developed. He was home with me after 2 days.

the baby takes 36 weeks to develop all the organs will not be fully developed until this time. if all the baby's development was finish at 4 months the baby chance at living at this time would be much grater and they wouldn't try to stop labor this early.

Actually it is about the first 3 months. After that they just grow bigger and gain weight. And all of their immature organs start to grow bigger and mature. But they don't grow anything new.

Yep, but the brain is also still developing after birth into the teenage years and even beyond. There are, however, things that develop after birth too; but as far as developing organs and such, it is about 4 months or so, then they get bigger.
