Your baby is now considered full term and is ready to be born any day. Your baby is now about the size of a watermelon and is typically around 20 inches long and weighs around 7 pounds.
After Birth: The First Year
After your baby is born, the first year of their life is full of rapid growth and development. Your baby will go through many milestones during this time, including rolling over, sitting up, crawling, and walking.
It’s important to remember that every baby develops at their own pace, and there is no right or wrong way to reach these milestones. The most important thing is to provide your baby with love, care, and support as they grow and learn.
