5 weeks: apple seed
Apparently this has been a big week for our growing baby! (Since we're almost done with week 5, I'm a tad bit behind with this info.)
Being 5 weeks pregnant, your little one is as large as an apple seed! Your baby's muscles, central nervous system and even bones start forming this week. Other important changes occurring during pregnancy week five include neural tube development. Your baby's skin, nails and even hair will also start to form in the top layer of cells. At this point your baby’s heart, no bigger than a poppyseed, has already begun to beat and pump blood. The heart is dividing into chambers and will find a more regular rhythm soon. Your baby is about a quarter of a centimeter long and looks more like a tadpole than a human. He undergoes a growth spurt this week.
Major organs, including the kidneys and liver, begin to grow. The neural tube, which connects the brain and spinal cord, will close this week. Your baby’s upper and lower limb buds begin to sprout – these will form your baby's arms and legs. The intestines are developing and the appendix is in place.
As early as this week, facial features are forming. Nostrils are becoming distinct and the earliest version of the part of the eyes that is sensitive to light (retinas) are forming.
Holy cats! No wonder I'm so tired, there's a lot going on inside me this week. Keep on keeping on Baby King! I can't wait to see you in SIX DAYS!
