Your baby now weighs nearly one pound! He or she measures 19 centimeters from crown to rump. Your baby now has eyelids and eyebrows and has developed fat, which helps to keeps it warm. In boys, the testes descend.
Almost all the follicles from which your baby's hair will grow are in place. Some babies are born with long, thick hair, others with almost none, but it will all fall out during the first months of life. Fingernails grow longer this month, and toenails are just starting to grow.
The number of nerve cells in your baby's brain increases rapidly this month, especially in the front of the brain, where thinking takes place. Your baby's system begins to produce the white cells that will enable it to fight illnesses and infections. The baby's senses, too, are beginning to awaken, and it may be able to hear sounds, such as the flow of blood, the beating of your heart, and the rumblings of your stomach.
Inside your baby's intestines, the first stool, called meconium, is forming. If your baby is a girl, eggs are starting to develop in her ovaries.
And, believe it or not, those teeny, tiny ears can now hear sounds from outside. She reacts to external stimuli like your caresses and voice.
