34 weeks pregnant

By the time you're 34 weeks pregnant, your baby is putting on weight in the form of fat to help them regulate their body temperature and to keep them warm after birth. Their bones are continuing to harden at this stage too. You should continue to eat a wide variety of healthy foods to support you both. Getting into good habits now will make it easier to continue eating the nutrients your baby needs once you start breastfeeding.

By week 34 of your pregnancy, your growing baby is roughly 5lbs in weight and 31cm long from head to bottom¹. Some of this additional weight is from their bones, which are continuing to harden and grow stronger. The exception to this is the bones in your baby’s head: these will stay soft and separated throughout pregnancy so that they can move and adapt safely to the pressure they will experience during birth².

Many of your baby’s body systems are functioning in week 34 of pregnancy but their immune system is still developing². It will continue to develop after birth, when your body will support this development, delivering protective factors, such as antibodies, in your breast milk².

If you were able to take a look inside your womb, you’d be able to see that your baby’s fingernails have now grown to the tips of their fingers. If you’re expecting a boy, their testes may be visible at this stage too, although a small number of boys are born with undescended testes. This usually corrects itself within the first year³.

With your due date drawing closer, now is the time to pack your hospital bag. Thinking ahead to what kind of snacks you might like during labour means you’ll be well prepared when the time comes. It’s worth remembering, too, that only 5% of babies arrive on their due date, so although it is a good guide to when your baby will arrive, it is just that – a guide¹.

Once your baby is born, your body continues to provide all the nourishment they need through your breast milk. Just as in pregnancy, your body will put your baby’s needs first, so it’s important that your diet includes the right balance of nutrients and energy to support you both.

“The healthy eating habits you’ve hopefully stuck to throughout pregnancy will be equally important once you start breastfeeding.”

Certain nutrients that are considered important during pregnancy are also vital for your baby’s development in their first few months of life, particularly:

• Vitamin D – supports healthy bone development in your baby’s body⁴. Continuing to take a vitamin D supplement beyond pregnancy will ensure you get the recommended 10mcg each day.
• LCPs, particularly DHA – contributes to the development of your baby’s brain and eyes⁵. You can get extra DHA by including up to two portions of oily fish in your diet every week.
• Iron – supports your baby’s cognitive development⁶, both now and beyond birth, and as a key component of red blood cells, is vital for transporting oxygen around the body. Iron-rich foods include meat; oily fish; leafy, green vegetables; and beans.

Another area you’ll need to pay close attention to while breastfeeding is your intake of fluids. The body requires a significant supply of water to produce breast milk and it is recommended that breastfeeding women have an extra 700ml of water daily above the daily recommendation of 2 litres⁸. That’s 10–11 glasses per day. Don’t forget, though, that tea, coffee, milk, fruit juice, soups and smoothies all count towards this daily amount.

You need plenty of fluids during these last weeks of pregnancy too, so if you have a suspicion you’re not drinking enough water, now is a good time to up your intake and establish a healthy drinking habit.
