      Extra helpings

      Your baby is preparing for life outside the womb in many ways. Learn how their lungs and nerves are developing in week 25 of pregnancy. To support the rapid growth and development ahead, you’ll need to add more calories to your balanced diet during your third trimester. Discover how many more you’ll need and how to get them, while maximising your nutritional intake.

      Your baby's development at 25 weeks

      Feeling hiccups at 25 weeks

      In week 25 of pregnancy, your baby measures about 22cm long from head to bottom and weighs roughly 700g (1½lbs)1. The umbilical cord is now thick and strong, with one vein and two arteries running through it1, delivering essential nutrients and oxygen to your baby and passing out waste for your own body to process2.

      You may feel your baby’s hiccups from time to time. These are a normal part of their development.

      With improved coordination, your baby can now make a fist and reach for their feet1, and you may feel them moving around in response to touch on the outside of your bump3. You may also feel the tiny rhythmic movements that indicate your baby has hiccups4.

      Internally, their lungs are getting ready for their first breath, and they are already producing surfactant, a substance that helps these vital organs function normally after birth4. Meanwhile, the nerves around their mouth are developing1. These will help your baby find your nipple by using the sense of touch in the early stages of breastfeeding1.

      Your baby’s hearing has advanced to the extent where they may now be able to recognise your partner’s voice and find some types of music more soothing than others.

      Add a little extra

      Now you’ve nearly reached your third trimester of pregnancy, you’ll need to increase your daily calorie intake to support your baby’s rapid growth and development. According to The Department of Health, women should have around 200 calories more a day in the last trimester of pregnancy5.

      …it’s important that your extra calories come from healthy, nutritious foods.

      However, everyone is different, and the amount of calories you need will depend on your metabolism, how active you are, and how many babies you’re expecting, among other factors. 

      Whatever your situation, you should still be maintaining a healthy, balanced diet, and it’s important that your extra calories come from healthy, nutritious foods.
