Welcome to the third trimester. This is the home stretch for you and your baby. The child inside you is still tiny, but she will double in size between now and her birth. Even more important, her brain will grow by leaps and bounds.

These months are heavy hitters when it comes to cognitive, or mental, development. By the end of the seventh month, your baby's brain will have the capacity of a newborn's. She will be able to see, hear, smell and learn. As strange as it may seem, during the last months of your pregnancy your child will share many of your daily experiences. Your alarm buzzing in the morning. Or the sound of the phone ringing and cars honking on the street.

Your baby is already discovering things about the world, and you're her guide. This unique relationship begins now. How it develops is up to you.
