Measuring your baby from top to toe with his legs extended, she may now reach 15 inches/ 38 centimetres; from crown to rump she is about 10 inches/25.5 centimetres. She weighs a little more than 2 pounds/ 900 grams.

Your baby's eyes begin to open around now. Response to sound grows more consistent toward the end of the seventh month, when the network of nerves to the ear is complete. She also continues to take small breaths and although she's only breathing in water and not air, it's still good practice for when she's born.

Since your baby is now growing so fast, and brain development is so intense at this stage, your nutrition is very important. Continue to eat a well-balanced diet that includes plenty of grains and vegetables. Fibre-rich foods, including whole-grain breads and cereals, lentils and brown rice are high in vitamin B and help fend off constipation.Your childbirth class should start sometime in the next few weeks, if it hasn't already. Classes should provide you with good, clear information about the birth and the early days of parenthood. Keeping informed goes a long way toward calming any concerns you may have about giving birth.
