Welcome to week 7 of your pregnancy! Your baby looks like a little bean. This week most of the development occurs in your baby’s head. The brain continues to grow and along with it your baby’s eyes and nose become more prominent.

So, let’s summarize the main events that you will see in this week

Along with the changes occurring in the baby’s head (eyes, nose, and brain)– the mouth also starts forming.

Your little one now sprouts limbs that are slightly webbed. They look like tiny flippers during this phase

Additionally, the transformation of the excretory system, by the development of the kidneys, prepares the waste management system of the baby.

The liver is now producing red blood cells and later this task is taken over by the bone marrow once it is fully developed.
