The ACOG (American College of Obstetricians and Gynecologists) indicate that a healthy baby usually has 10 kicks within 2 hours. Most babies will take less than 30 minutes.
Every pregnancy and every baby is different. The most important thing is keeping counting every day to monitor your baby’s health.
If your baby’s kicks less than 10 times in 2 hours, or you notice the “unusual” changes, don't be hesitate to call your doctor!
