Your babys progress - Week 6
That little being growing inside you looks more like a fish, a tadpole or even a manatee than a human baby by week 6 of pregnancy. In the days after conception, that little tadpole has been tightly curled up but this is the week baby’s trunk and neck start to grow and straighten and that fishy little tail recedes.
Baby now has an oversized head and dark spots where eyes and nostrils will form and there are tiny depressions on the side of the head that will emerge as ears. Baby’s heart is beating about 100 to 160 times a minute, almost twice as fast as yours! Baby’s heart beat can now be seen in an ultrasound. Blood is beginning to course through baby’s teeny body and there is the beginning of organs like a digestive system and lungs.
Your baby's limbs start to lengthen this week to form arms and then legs, with their hands and feet resembling little paddles, that will eventually become fingers and toes. Their internal organs are also taking shape, with stomach, kidneys and bowel now defined, as well as 2 small buds which will form into lungs. Just like grown-ups, embryos grow and develop at varying rates, but you can assume baby is roughly the size of a lentil or around half a centimetre.
Just like adults, all babies are different and develop at varying rates in the womb. This information gives a general idea of your baby's development and progress.
