•Hair and nails: Between week 7 and 8. The skin begins to form with hair follicles. Around week 8 the nail beds start forming.
•Digestive system: By week 8 the baby’s intestines will begin to form, the baby will have already gone through two sets of kidneys; there is a third and final set on its way.

•Eyesight: Optic nerves and lenses begin to form by week 4, around week 8 the retina begins to form.
•Heart: The tube that becomes the baby’s heart begins to beat spontaneously by week 5. It will become stronger and more regular and around 9/10 weeks and you will be able to hear it at a screening test with your health worker.
