The end of your second trimester
As you come to the end of your second trimester, in week 26 your baby measures around 23cm from head to bottom and weighs roughly 2lbs1. Their spine is now becoming stronger, providing the support needed for their growing body. Meanwhile, the lungs continue to mature in preparation for life outside the womb2.
Getting ready for your baby's birth
As your baby starts to prepare for their birth, it’s a good idea for you to do the same. Now’s the time to start thinking about your birth plan: using our ‘Preparing for Birth’ app will provide you with everything you need to feel ready and confident about your baby’s arrival.
If you haven’t already told your employer that you’ll be going on maternity leave, you should do so now, as you need to give them at least 15 weeks’ notice. Find out more about maternity and paternity leave at direct.gov.uk or worksmart.org.uk.
LCPs on the brain
Long chain polyunsaturated fatty acids (LCPs) are a group of special fatty acids. Two of the most significant LCPs for your baby’s development are called DHA and AA, which are part of the Omega 3 and Omega 6 groups of fats3.
DHA has been shown to contribute to your baby’s brain and eye development and is important for your baby’s visual development throughout their first year of life4.
"Because your baby’s brain develops so rapidly in your third trimester, making sure they get enough DHA is particularly important."
DHA continues to support your baby’s brain development after birth when it’s passed on through your breast milk5.
Experts have reviewed the evidence relating to LCPs in pregnancy and found that mums who took extra DHA in the latter half of pregnancy reduced their risk of preterm delivery and increased the birthweight of their babies6,7.
Good fat facts
It’s important to make sure your balanced diet includes good sources of LCPs, particularly DHA, while you’re pregnant and once your baby is born, too.
Experts recommend including an extra daily dose of 100-200mg DHA during pregnancy and lactation8. However, food sources of DHA are limited to oily fish, fish oils and offal, some of which are on the list of foods to avoid or limit during pregnancy, particularly liver.
For a healthy intake of LCPs including DHA, aim to eat 1–2 portions of oily fish, such as mackerel, sardines, fresh tuna and salmon, per week. Avoid eating more than this due to the levels of pollutants and mercury they may contain.
If you don’t like the idea of eating oily fish be sure to include some other sources of Omega 3 fats in your diet such as nuts, seeds, dark green vegetables, rapeseed oil, wholegrain cereals and soya products9.
Try these pregnancy meal and snack ideas which provide Omega 3 fats:
- Mackerel on a slice of wholegrain toast
- Grilled salmon with steamed vegetables
