Before you even took your pregnancy test, your body had already begun knitting together what will become your baby’s brain. The neural tube, the building block essential for a healthy spinal column, starts forming at five weeks -- about the time most to-be-moms realize they missed their period. Then, brain development continues at a furious pace (which might explain why you feel so tired!). After all, there’s a lot of work to do to make sure that in about 40 weeks, your baby will be ready to experience and react to the world around him. So how can you make sure that your baby starts life with the healthiest brain on the block? Try these brilliant strategies.
