By the end of this trimester, your baby's brain may be three or four times larger than it was at the start. To support its astonishing leaps in size and function, his brain demands extra nutrients. One of the most important is DHA, an omega-3 fatty acid commonly found in fish. This vital substance helps your baby's brain cells grow larger and develop a crucial insulating sheath of myelin, which helps speed up communication pathways in the brain. Fatty acids are uniquely concentrated in your baby's brain during the 3rd trimester, so this is a great time to boost your baby's DHA levels with extra helpings of fish, canola oil, or flaxseed.
