You typically start feeling your baby move between 16 and 25 weeks of pregnancy. If this is your first pregnancy, the movements might be felt closer to 20-25 weeks, while in subsequent pregnancies, some women feel movement as early as 13-16 weeks. These early movements are often described as flutters or butterflies. The movements become more distinct and frequent as the pregnancy progresses, especially by the third trimester when the baby moves about 30 times an hour. It's best to notice these movements when lying down or sitting quietly. If you have not felt any movement by 24 weeks, it is advisable to consult a healthcare provider. Regular movements throughout the day are a sign of your baby's well-being.
