25 Weeks

I am a bit late with my 25 week update!!

But, first, wanted to share the good news that Baby View called us about our session and have offered to allow us to come in free of charge to see if we can get some better 3D and 4D pictures!!! So, I figure we can wait a few weeks to give Sydney a chance to move and get a little bigger and easier to see!

On to the update:

You are now 25 weeks pregnant which is the beginning of week 26. Your baby measures about 33 cm (or 13.2 inches) and weighs about 800 grams (or 1lb 12 oz). Their eyelids are no longer fused so they can now open them and even blink! It is possible for your baby to respond to bright light (such as shining a torch through the woman’s belly). Newborn babies have vision that is perfectly focussed from about 20 to 30 cm (usually as far away as the face of the person holding them!)

Your baby can now recognise your voice and be noticeably calmed by it (observed by their heart rate slowing). They can also recognise your partner’s voice and different types of music. From observing unborn babies with ultrasound it has been shown they may respond to relaxing and classical type music by turning towards it and curl up and away from very loud rock, rap and pop type music.

Your baby’s movements are generally more regular now and they may physically respond to you if you press on parts of their protruding feet, bottom or hands. Some parents will play ‘games’ with their baby at times when they seem awake and alert! Your caregiver can now hear your baby’s heartbeat with a Pinnard’s stethoscope (rather than just an electronic Doppler) and it beats at about 120 to 160 beats per minute.

Babies born between 24 to 26 weeks are regarded as being extremely preterm, but have about a 50 to 70% chance of surviving if they have access to specialised care and a fully equipped intensive care nursery.
