Baby is now the size of a rutabaga
Welcome to Week 25. Your baby is growing steadily and becoming stronger every day. Movements may now feel powerful enough to make your belly visibly jump, and you may be getting to know your baby's unique patterns and personality. For many mothers, pregnancy is becoming more physically demanding as the bump grows larger and sleep becomes more challenging. The third trimester is getting closer, and the excitement of meeting your baby may feel more real than ever.
