The complicated structure of your baby's eyes is continuing to develop, and the baby will now turn in response to a light being shone through the womb. The eyelids are no longer shut, and your baby can make blinking movements.
If mums are thinking of travelling by plane after week 25, you may need to provide a letter from your GP to say that you are fit to travel. This is because flying after this time increases your risk of high blood pressure and premature birth. Airlines all have slightly different policies but usually you should be able to travel up to week 28, and if you are flying for less than 4 hours you should be able to travel until week 36.
Rarely, high blood pressure may be a sign of pre-eclampsia. Pre-eclampsia is a serious condition, which can be very dangerous to both mum and baby. The cause of pre-eclampsia isn't fully understood but you can help prevent high blood pressure by eating a healthy diet with less salt, exercising regularly, quitting smoking, and reducing alcohol and caffeine intake.
