25 weeks......

Your baby's crown-to-rump length is about 33 cm and the weight has increased to around 800grams and fat is still being deposited at a high rate.
The baby's eyelids are no longer fused, so they can now open their eyes and blink! It is also possible for the baby to respond to bright light (such as shining a torch through the belly). Newborns have vision that is perfectly focused from about 20 to 30 cm, usually as far away as the face of the person holding them!
