Mom's Changing Body

Does your belly feel a bit lighter these days?

In a first-time mother, the baby often "drops" two to four weeks before delivery.

Even if you don't start having contractions immediately, your baby will need to be delivered in the next 12 to 24 hours to reduce the chance of infection.
