Week 16….or is it 17?

Laura had her sonogram yesterday and they aid that as of yesterday the baby weighted 6 ounces!  What a chub!  🙂  She also said that the baby was measurering at 17 weeks yesterday!  So who knows when the due date it now.  I am so excited to know the baby’s sex so I can star shopping!  I am working on the video of the sonogram and will post it soon!

Week 16/17


Week Sixteen

  • Fat begins to form underneath skin, providing your baby with insulation for the coming months.

  • Did you know that both baby and placenta are now about the same size?

  • Your little one has reached 4.57 inches (11.6cm) and approximately 3.53 ounces (100gm).

  • His head and neck are held straighter now.

  • This is a week of “mights!” You might hear the tiny thumps of his heartbeat with an external monitor now. The genitals are developed sufficiently that an experienced sonographer might be able to determine if your baby is a boy or a girl.

  • Her heart is pumping as much as 6 gallons of blood a day and beats at a rate about double your heartrate.

  • If you could take a peek inside, you would witness your child’s reflexes in action! (Sucking, swallowing and blinking are now evident.) She is probably even hiccuping even though you don’t feel it yet!

  • Your baby has learned to breathe! This is apparent from the regular movements of his chest. Isn’t it amazing that he is able to breathe “underwater,” inhaling and exhaling small amounts of amniotic fluid? These actions help the lungs to develop and grow.


Week Seventeen

  • By week 17, your baby weighs about 4.97 ounces (140gm) and is 5.12 inches (13cm) long.

  • He or she has a much more normal “human” appearance now. She holds her head more erect and her body and limbs are longer in proportion to her head.

  • Pads are forming on his tiny fingertips and toes. Soon those individual swirls and whorls will be apparent.

  • Her eyes are looking forward now, but they are still firmly closed.

  • Meconium (composed of products of cell loss, digestive secretion and swallowed amniotic fluid), is accumulating in the bowel. This black gooey substance will become your baby’s first poop!

  • The umbilical cord is growing thicker and stronger and continues to rush blood and nutrients to your growing baby.

  • If your child is male the prostate begins to develop.

  • Her skeleton is tranforming from cartilage to bone. The bones remain flexible to make the journey through the birth canal easier.
