The second trimester of pregnancy is probably the most fun and the most exciting for parents, particularly the first timers!

Mom and her partner may learn the sex of the baby during this time, as usually a second sonogram is performed during these months. Baby may be shy, however, so the answer still may be a mystery until birth occurs.

Mom's belly begins to pop and maternity clothing becomes more comfortable to wear than stretch pants and an oversized tshirt. Comfort is the key here, but style does not have to go by the wayside. Maternity outfits have become more "corporate" over the years, so Mom can look stylish while remaining comfortable up until the delivery.

It's important to ditch the high heels, however. The changes in Mom's body require firm ground under her feet, so stylish and comfortable flats are important to prevent unexpected falls. Moms should not be surprised if shoe sizes extend by one-half to one full size larger at this time. This is usually not permanent, but the body's way of providing a safe base for baby's rapid growth.

Tiny waves begin to happen during this time also and usually extend to definite movement and kicks by the end of the second trimester. Moms do not always notice the flutters, but those are the baby's way of announcing that he or she is there and wants attention!

Hips may become sore as they begin to expand to prepare for the baby's birth. This normally is more prominent in smaller boned women, but can happen to anyone. While it is always important to consult the doctor when feeling anything unusual, these aches are a normal part of the pregnancy process.

Cravings may begin now also, or may have begun in the first trimester. While it is crucial that the mother-to-be keeps to a nourishing, balanced diet, a craving can be indulged occasionally, particularly if it is for a fruit or vegetable.

No smoking or drinking should occur at any time during pregnancy. Secondhand smoke should be avoided as well, as what is inhaled goes straight to baby!

Second trimester moms may feel more tired or may experience bursts of energy during this phase of the pregnancy. It is important to remember that everyone is different and that there is no set norm. If Mom is tired, she should nap. If she is energetic, she should remain active.

Exercise is important, but only familiar exercise. This is not the time to begin a Pilates class for the first time!

This is the time to celebrate the changes and anticipate the final result--a brand new boy or girl!
