If your baby isn’t moving as usual, you might do a “kick count”. Lie down on your side. Set a timer, and see how long it takes for the baby to make 10 movements. The American Congress of Obstetricians and Gynecologists (ACOG) says it’s ideal to feel at least 10 movements in 2 hours.  Babies often have quiet periods. So, according to the ACOG, sometimes it’s ok not to feel 10 movements in 2 hours. But a significant reduction in movement can be a concern. If you feel your baby is moving less or the movements are weak, call your doctor. It’s always better to check with a doctor than to wait too long.
