During this week, the baby proceeds to steadily add weight and insulate fat layers to his/her body.
Brain of your baby continues to develop and expand, forming extra folds and grooves in the surface of the brain. These wrinkles provide the brain tissue with the required space to expand, as the baby develops and learns.
