SEVENTEEN WEEKS PREGNANCY

SYMPTOMS AND BABY SIZE

HOW YOUR BABY GROW

Your baby is now nearly 13cm from head to bottom and weighs the same as a turnip. about 140g . His unique fingerprints have now finished forming, and his hearing is improving every day/ If you play music he may even move around in your womb.

 A white fatty substance called  myelin is slowly wrapping around your baby's spinal cord.  Mylin is important as it helps speed up messages between your baby's brain  and the nerves around his body. It also   provides  protection and insulation to his nerves.

 Your baby's recent growth means his head and body are more in proportion than they were in earlier weeks. His skeleton will continue  to harden from rubbery cartilage to bone. As he gets bigger. the umbilical cord his lifeline to your placenta, grows stronger and thicker.
