Week 3
*You’ve conceived and your soon-to-be-baby has started on its miraculous transformation from single cell to baby boy or girl.
*As sperm meets egg, fertilization occurs and your baby-to-be takes form — as a tiny group of cells.
*This week, the fertilized egg — or zygote — divides several times over to become a tiny ball of microscopic cells smaller than the period at the end of this sentence.

Week 19
*Your baby's sensory development is exploding!
* Her brain is designating specialized areas for smell, taste, hearing, vision, and touch.

Week 26
*The network of nerves in your baby's ears is better developed and more sensitive than before. He may now be able to hear both your voice and your partner's as you chat with each other. *He's inhaling and exhaling small amounts of amniotic fluid, which is essential for the development of his lungs.
*And he's continuing to put on baby fat.

Week 29
*Your baby now weighs about 2 1/2 pounds (like a butternut squash)
*Is a tad over 15 inches long from head to heel.
*His muscles and lungs are continuing to mature, and his head is growing bigger to make room for his developing brain.

Week 33
*This week your baby weighs a little over 4 pounds (heft a pineapple) and has passed the 17-inch mark.
*He's rapidly losing that wrinkled, alien look and his skeleton is hardening.
*The bones in his skull aren't fused together, which allows them to move and slightly overlap, thus making it easier for him to fit through the birth canal.

Week 36
*Your baby is still packing on the pounds — at the rate of about an ounce a day.
*She now weighs almost 6 pounds (like a crenshaw melon) and is more than 18 1/2 inches long.
*She's shedding most of the downy covering of hair that covered her body as well as the vernix caseosa, the waxy substance that covered and protected her skin during her nine-month amniotic bath.
